KML Statistic

[Valentin]

Hello everyone,

i'm doing a project for the university and got stuck with a problem. I
have to color prices like this webpage

http://www.nelso.de/beer-price-map-of-prague/

When the price is cheap it should show green and when its expensive
red. I can do a static drawing and laying it over with KML but how or
is it even possible to generate this dynamically??

Because it is possible that the price can change and so the color.

I assume it is possible to make buffers around the location and color
them... but then there would be circles and circles which doesnt look
pretty good.

I hope there are ways with KML to generate that, or do you know any
other program languages to generate this dynamically. I though of
Matlab but i'm not quite sure

Hope you can help me.
With best greets
Valentin

This link describes how to create a heatmap and than save it as a kml:

Thanks alot in fact i don't have any clue how to get this dynamically.
Is it possible to use Python over a server? So if a price changes it
colors automatically again?

Thanks alot again

Maybe there are ways with javascript via openlayers or php to solve
that?
