Heat maps with Python and Inkscape | oCoCarbon. Mel Starrs tweeted a week or so ago about using GIS software to do mapping and energy analysis. I wanted to do the something similar but for sub-metered zones in a multi-tenanted office building. Rather than go down the route of learning a new package, I remembered a chapter on creating choropleth maps in Nathan Yau’s fantastic Visualize This.

I will try to start with some basic ideas and exercises to improve this kind of understanding. Let me start by clarifying some common believes when it comes to creating game at.

With version 0.46, Inkscape released a new feature called “pattern along path”, which amounts to what you would call brushes in Adobe Illustrator. Although there are a few big differences in using brushes in Inkscape, it’s relatively easy to get the hang. I’ll walk you though how make and use brushes for your drawings. Create a new drawing Open up Inkscape (you’ll need to be using version .46 or higher).
It’s a good idea to edit the document size (CTRL + SHIFT + D) to what ever you’d like the final design to be used for.
