  • Introductory notes: "Maps & map projections"
    • "Maps" To give a quick lay of the land, I see this as a few major niches of maps in this space: static maps, like those in Mike's "Let's make a map" tutorial, dynamic maps with local data, like those in Jason's "Rotate the World" example, and dynamic maps with worldwide data, like those in Mike's Zoomable Map Tiles example.

    • "Map projections" To give a quick lay of the land, d3-geo provides a rich set of projections, and d3-geo-projection provides an even more rich set of projections to the savvy d3 user. Map projections are different methods for smooshing a bumpy, mostly round earth onto a flat computer screen. They're the topic of much discussion by cartographers: the most popular projection for web maps, and the one you'll see on Google & Apple's maps, is Web Mercator, which is, roughly, despised by monocle-wearing cartographers. I've written some things about this: "Understanding map projections", "Project it yourself", and so on. Also if you want to google "Mercator racist" you'll get results.

  • Ask everyone
    • Who comes from a mapping-centric background?
    • If people have a favorite map projection, what is it? If your favorite is Mercator, don't answer - silence means Mercator.
