Mapping the UK's oldest trademarks, part 2.

The second of two parts, this video covers the front-end steps in creating a map of the UK's oldest trademarks.

Here we visualise the trademarks data we gathered in part 1 using D3js by rendering a map of the UK with postal area boundaries, labelling and then filling with the oldest trademark for the area.

We begin with this starter template, and finish with this visualisation. The map we create in the screencast represents about 70% of the work that went into the final visualistion which you can check out over here.

You can find the code for both steps, plus the final visualisation on Glitch!
