I would love it if was possible to download the rendered chart, ideally headless. In peak traffic I would prefer to switch to a pre-rendered version, have the pre-rendered version available encase of an error (i.e. data retrieval), or for users not using JS.

After the most minimal Google-foo, I see echarts-python [1] which has not been updated in 9 years. pyecharts [2] is looking pretty well maintained though.

Years ago I tried my hand at writing a simple bar/line plotting filter for Pandoc that embeds itself into documents via an SVG in a URI [3]. If HN is permitting, you can past links like so [4]. I think writing a stand-alone tool to display the data you are interested in is a good idea for anybody.

You can easily download a rendered chart by using the chart's getDataURL() function. Then just create a new element in your document and set that element's href to the return from getDataURL() and bob's your uncle.
