Is there any way to embed any of the graphs from Github (any of the 4 found at https://github.com/Vizzuality/CartoDB-SQL-API/graphs)? For example, this one showing the changes in the lines of code.
Since the structure of the page is consistent, I'm pretty sure I can scrape it, but that's a bit cheeky at best. Note that I want the image itself - not the whole page - that is contained in the div:
<div class="graphs wheader">
This question is the nearest thing I've found for this, but obviously doesn't apply for Github. Would rather not reinvent the wheel!
PS: that's not the project I'm interested in embedding, it's just that that one has enough data on it to show.
Those graphs are built dynamically via javascript (d3.js) and SVG. This makes them fairly difficult to extract. However, you might be able to recreate them; inspect the javascript resources on the given page which are used to build the graphs.

Does anyone know if I can integrate GrapeJS into my own website so clients could build their own websites using it? IF anyone has done this, how easy is it and are there downsides?
This question is pretty open ended, but I'll take a shot at it.
The short answer is yes, you can use Grapesjs to allow clients to make their own sites; however, the details matter.
Grapesjs by default doesn't know anything about your stack, website structure, metadata, etc. You will need to either supply plugins or implement those features yourself. I've worked on a project for a company that used Grapesjs to implement single page apps and I'll include just some of the tweaks we had to manage.
Hiding certain layers that only confuse average users.
Hiding pretty much all of the styling, and using traits to allow people to pick from some predefined styles.
Take the html, css on store and generate the final html page, and store it in our static serving folder on the server.
Implement a wrapping "App" component that has traits for the different metadata we want users to control (open graph metadata, title, etc)
and those are just the big things, I'm sure I am forgetting several small ones.
For your application, you'll also need to implement a custom trait for links / buttons that allows you to link from one "page" to another. As well as, a way to allow a user to pick which page to work on.
The long answer is Yes, but Grapesjs is only the starting point.
Yes you can.
However it is not straightforward.
If you want to build a Drag Drop Editor like GrapeJS Demo, here is the Source Code - https://github.com/artf/grapesjs-preset-webpage

I need to embed both pdf-files and images in my html-page, however, due to the fact that my html contains a form and the user has to be able to decide whether he would like to upload a pdf-file or an image, I need a flexible solution regarding how to embed either a pdf-file or an image with the same code.
I read that I could possibly use the <object/> tag, however, I also read that that's not a very "elegant" and possibly slow solution.
I also considered to use <embed/> which, as of right now, is the best solution I could come up with. Unfortunately I couldn't find out about if it's a very conventional solution or not.
I can't seem to find very much resources regarding this topic online, hence why I'm asking here. Are there any other/better ways to embed a pdf- or image-file in an html page?
Edit: I want top display the pdf kind of like a file. Also, I don't want the user to be able to resize the pdf in the viewer
I'm sure this is better suited to a comment, however I'm new and am working on unlocking that feature.
...however,
due to the fact that my html contains a form and the user has to be
able to decide whether he would like to upload a pdf-file or an image...
What are you using for the form (query language & database management)?
(PHP, Django, MySQL, MongoDB, etc)
Are there any other/better ways to embed a
pdf- or image-file in an html page?
I would recommend using embed or iframes. You are correct in thinking that the object tag is not an elegant solution, since you are dealing with images.
Edit: I want top display the pdf kind of like a file. Also, I don't
want the user to be able to resize the pdf in the viewer
Easy to do with iframes. There's a lot of hate when it comes to iframes. As you seem to plan on using it as a tool to display a file within a page, then I believe using an iframe here is just fine.
Check out this link on iframes. (will also tell you how to keep the user from resizing it)
In my rails app I have a need to save some webpages and display them to the user as images. For example, how would I save www.google.com as an image?
There is a command line utility called CutyCapt that is using the WebKit-Rendering engine to render HTML-Pages into various image formats. Maybe this is for you?

Prohibitively difficult to do in pure Ruby, so you'd want to use an external service for this. Browsershots does it, for example, and it looks like they have an api, although I haven't used it myself. Maybe someone else can chime in with alternative but similar services.
You'll also want to read up on delayed_job or something similar, to make sure you're accessing those page images as a background task and that it doesn't interfere with your actual application.
You can't do it easily (probably can't do it at all).
Each page is just a text - html data. The view you want to make an image of is a rendered page. Browser renders the page using tonns of techniques like html parsing, javascript parsing, css parsing, font rendering, etc.. To make the screenshot of google page - you would need to do all the rendering somewhere in memory and then take a screenshot of rendered page.
That task is almost impossible (there is nothing fully impossible).
If you are really eager to donate tonns of time to accomplish that task - you should do this steps:
1) Find some opensource rendering engine. Firefox would do.
2) Find some way to communicate between ruby-on-rails and that engine.
3) Wire it all together and see the results.
However, I see steps 1 and 2 as nearly impossible.

A graphic designer created a web page design and I have it in PSD now.
What are the tools or techniques used to easily convert this image into HTML.
to get the best result you need to code up the html yourself integrating the relevant graphics when needed. if you are unable to do this yourself there are quite a number of companies that will take a PSD and code it into HTML for you. One example being www.psd2html.com - do a search on google for more examples.
check http://www.bolducpress.com/tutorials/from-photoshop-to-html/ for a great tutorial about "slicing" which is one technique to "convert" a psd-file to a webpage.
Use the Slice Tool to slice up the psd file into chunks of graphics that can be layed out on a web page. Then choose Save for web... to save these chunks into individual jpeg, gif or png files.
Have it sliced if you must, but better build carefully planned HTML by hand, or have it done for you.
There are slicing tools that others will be able to tell more about. I personally think there is no better way really than creating the basic HTML and CSS by hand. Because what you build now is the foundation for your entire web site, and any future extensions to it, it is really worth the effort.
If you go this route, you would pick a normal HTML editing program or platform and sketch out the basic structure according to the layout you have.
If you have little experience with HTML and need to get the job done, try out a slicer. If you have time and/or money, work it out by hand, use a high quality template as a basis, or have it done professionally.
Whilst I would agree with all of the comments above, if you want to do this yourself or don't have the knowledge/funds, you can do it with the likes of Dreamweaver/Fireworks, but as everyone has said, you won't get good HTML and unless you use it properly you'll have problems if you ever make changes to your page as changing sizes will break your layout.
I'm learning web dev and I am already stucked at some point..
How do I convert a PSD template to a html/css website ?
I've cropped all part of the image and saved them in .gif separately, but then ? Do I have to manually place them in a dreamweaver empty template ? I thought there was an automated way to do so..
Also, I've tried "Save for web and devices.." but when saving, it creates a .html file and a single image which contains every element ?! I expected several images so that I could rearrange them in dreamweaver.
While certain applications advertise/provide automation of the "conversion" process from composite graphic to web layout you want to avoid using those features. They will cause you more trouble than they are worth. Especially if you are going to use CSS for layout (which I strongly encourage). Thats not to say those features dont have some limited valid usages (more on this in point 2) it just that they arent going to magically generate your site from a graphic.
In order to use "Save for Web..." you need to use the Slice tool to slice down the image into the different images you need for layout. Then when you do save for web and deices with html it will export the html/css and the images. Again this isnt magic and chances are youre going to have to completely redo most of what its done for you - making it useless for anything more than slicing a certain area of the layout (say a single menu).
There isnt a fully automated way to do this, generally speaking because depending on what you need the layout to do you have to go about laying things out in different ways and while its theoretcially possible to account for all the possible potential requirements in a nice little export GUI its not really feasible.
The bottom line is to do this you have to learn HTML/CSS. And the more you learn the more you will hate Dreamweaver (at least in "layout view"). Garaunteed.
Yea, web design doesn't work by magic. The proper way to do is to manually write the actual code that positions the elements, not just smack them in place in Dreamweaver. There's plenty of good tutorials out there, check these out for example:
http://net.tutsplus.com/videos/screencasts/how-to-convert-a-psd-to-xhtml/
http://www.devwebpro.com/creating-css-layouts-the-best-tutorials-on-converting-psd-to-xhtml/
Welcome to reality.
You'll have to slice and dice yourself (well, slice and dice the image yourself, but don't slice yourself no matter how much you want to), and then place each individual part in your HTML or template.
There are a number of automated services that convert PSDs for you:
http://converxy.com
http://psd2htmlconverter.com/en/
http://www.psdtoweb.de/
http://csshat.com/
However, you might also want to consider a service-based approach as well. There is a thriving community of professional slicers out there (just google "psd to html" and you'll see what I mean).
You might also try to redesign from a program or framework such as:

http://foundation.zurb.com/
http://getbootstrap.com/
http://www.awwwards.com/what-are-frameworks-22-best-responsive-css-frameworks-for-web-design.html
It really depends on your budget, your timelines and your skillset.
I'm a big proponent of understanding something really well before trying to automate it. So, like the other posters have said, slicing by scratch (handcoding) is very valuable, especially if you don't already understand it well. However, you might just not care to invest the time needed to achieve a good understanding of the subject. And, that's perfectly okay too.
I think that ad the end of the day, there is no "correct" solution. Different people have different requirements which will change the choice.
This may help you, it walks you through the process.
