This session is sponsored by "JSON’s Not Cool. You Know What’s Cool? TopoJSON"

TopoJSON is a wonderful way to display choropleth and other maps and geo-visualizations. It doesn’t require a backend, it works great on mobile (small load sizes!), and the underlying technology is just plain cool. That said, there’s a bit of a learning curve. In this session, we will work through the basics. After acquiring GeoJSON, we will convert it to TopoJSON, load it up in a browser, style it, then put it on a public repo where we can see it from our phones! For people who have an intermediate-level understanding of JavaScript and some experience with D3. Bring your laptop and a power cord. Please note the capacity for this session is 90 participants. Seating will be provided on a first-come, first-served basis.
