"Last year, I volunteered to make ta webpage for a kids' charity in México. Everything was pretty standard, but the staff wanted some data displayed as pie charts on their landing page. They didn't give us a lot of time, so I admit I took the easy route and used one of the many JavaScript libraries out there for making charts."
"In order of priority: This must be semantic! Meaning a screen reader should be able to understand the data shown in the pie chart. This should be HTML-customizable! Once the CSS is done, we only have to change the markup to customize the pie chart. This should keep JavaScript to a minimum! No problem with JavaScript in general, it's just more fun this way."
"We can't talk about pie charts without talking first about conic gradients. If you've read anything related to the conic-gradient() function, then you've likely seen that they can be used to create simple pie charts in CSS. Heck, even I have said so in the almanac entry. Why not? If only with one element and a single line of CSS..."
A volunteer built a webpage for a kids' charity in México and used a JavaScript chart library to render pie charts quickly but felt the solution was excessive. The objective shifted to crafting a perfect pie chart in CSS while minimizing JavaScript. Priority requirements include semantic accessibility so screen readers can interpret the data, HTML customizability so markup changes control the chart, and keeping JavaScript minimal. The approach evaluates conic-gradient() as a common CSS technique for pie charts while acknowledging its limitations and seeking a more handcrafted, lightweight solution.
