Two years ago I re-vamped my "Spurious Correlations" side project, which is mostly just a bunch of charts. However, I couldn't find a charting software I liked that would display clean, simple visuals with the constraints I wanted. (I had used pCharts and HighCharts in the past, but didn't like charting in Javascript or PHP.)
I decided to "roll my own" and write Python scripts that outputted SVG markup. I was worried this would go about as well as every other "roll your own" project does, but was pleasantly surprised. It is surprisingly easy to output reliable, good-looking SVG graphics using Python. If you are making a chart, everything is just math.
The infinite scalability is almost just a happy upside to the simplicity of creating the visualizations, which is annoying in raster format. It made me like SVG even more.
