Other than that the graphs look good, I don't have much to say about the code (not a Python person), but I think the approach is great, mostly because I like using custom-generated SVGs for visualizations myself as well.<p>The <i>only</i> downside I've experienced is that it's pretty much impossible to get data-dependent interactions (tooltips and clickable links that vary based on section) to work reliably: additional Javascript has gotten me to like 80% on desktop, but not on mobile.
