How can I add a really small placemark to KML file? - a tiny dot or something similar.
I have set of positions (latitude and longitude) that I can add to a KML file to create a 'heatmap'. I'm adding each position as a placemark, as I add more and positions to the file I can build up a heatmap showing cluster of positions and density.
The problem is that the icons (for example the default yellow pin) are simply too large. Is there any way to add a single dot or tiny marker? just a couple of pixels across would be fine.

Are you looking for something like this?:
KML:
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.1">
<Document>
<Style id="measle">
<IconStyle id="measle">
<!-- specific to IconStyle -->
<scale>1</scale>
<Icon>
<href>https://maps.gstatic.com/intl/en_us/mapfiles/markers2/measle.png</href>
</Icon>
<hotSpot x="0.5" y="0.5"
xunits="fraction" yunits="fraction"/>
</IconStyle>
</Style>
<Placemark id="pm123">
<styleUrl>#measle</styleUrl>
<name>point123</name>
<Point>
<coordinates>-95.44,40.42,0</coordinates>
</Point>
</Placemark>
<Placemark id="pm456">
<styleUrl>#measle</styleUrl>
<name>point456</name>
<Point>
<coordinates>-95.43,40.42,0</coordinates>
</Point>
</Placemark>
</Document>
</kml>
