They should check out Vega – A Visualization Grammar - https://vega.github.io/vega/

When does it get too abstract? What’s wrong with plotly? Or plotly express? How is yet another JSON spec era-anything?

Why is this "for the AI era"? Isn't it kind of not for the AI era since an LLM can create a gnarly python or js chart of whatever you want in seconds?

https://www.highcharts.com/demo is still the best charting library out there.

The charts look clean, the design is consistent, there are no weird borders or unnecessary whitespace, and the tooltip system is excellent.

I’ve used Highcharts for 10+ years and have never found it missing a feature compared to any of the alternatives people have built over the years (https://en.wikipedia.org/wiki/Comparison_of_JavaScript_chart...). There’s always something off about the would-be replacements.

D3.js (https://d3js.org) wins on sheer engineering prowess, but it takes far too long to get a chart rendered.

Plotly (https://plotly.com/examples/) works too, but it’s less accessible than Highcharts.
