D3.js Choropleth Map Code Walkthrough

Maps are some of the most shared and sought after forms of visualisation. For this second video, I walk through an example that visualises unemployment data at the US county level. The code was updated from this bl.ocks.org v4 example to use d3.js version 7. The walkthrough touches on using d3-fetch to retrieve data on the web, as well as some basics of rendering geographic data.

Thank you for this presentation, I like the way you split the different parts of the code and explain what's its part of like ES6, D3.js. Thanks for explaining the difference between TopoJson and GeoJson.

[@creatingwithdata]

You're welcome! And thanks for the feedback- it's really useful to know what works! Do let me know if there are any other d3js examples or topics that you'd like to see. I'm going to be recording soon :)

Can D3-fetch@3 hosting space be replaced by GitHub? Basically, I'm asking if JSON file could be hosted on github, be parsed, and fit into D3 rendering functions? Would be very helpful if you responded, thanks in advance!

[@creatingwithdata]

Although Github isn't intended for this purposes it's possible to host JSON file, and then you could use d3-fetch to request the data.

True! I've been busy with a sideproject that's kept me from recording. I have recently got back into posting on the blog - creatingwithdata.com/
