Turning polygonal badges into contours of practice

A few weeks ago, I shared a post in which I suggested that badges-as-radar-plots could change shape as someone's skills develop. A bit like a mini e-portfolio, rather than a single snapshot image. That post got a lot of interest, so I've been experimenting with a tool, which I initially based on Badge Studio, to take things a step further. The result is Contours, a usable work in progress that provides an easy way to turn data into a layered, topographic-style view of a learner’s skills progression over time. The example uses the DigComp 3.0 framework but you can define the axes and values yourself. The tool draws contour lines that, as you can see in the gif at the top of the post, can show things like an initial, midpoint, and and endpoint assessment on the same badge image.Although the Open Badges v3.0 standard doesn't require an image, I still think it's usually a good idea to include one. And the good thing about this version of the standard is that the evidence of progression is…
