XY charting library

What hackers pick instead

• ChartGPUFast WebGPU charting library that renders a million points smoothly in the browser. Critics say sampling can hide peaks and that sliders and zoom controls misbehave.35recommend
• ggplot2People recommend it for a consistent grammar-of-graphics approach that makes almost any chart, but critics find extensive customization hairy.29recommend
• plotnineA Python port of ggplot2's grammar of graphics, liked by people who know ggplot. One critic objects to using the '+' operator to build plots.22recommend
• ggsqlLets you plot charts directly from SQL using a ggplot-style layered grammar. Main caveat: critics say the docs are thin and it adds little beyond R or Python.19recommend
• MatplotlibFree Python plotting library that people rely on for charts and data visualization; critics find its API verbose and slow with large data.17recommend

1. Moving reduction into Rust and sending screen bounded data to WebGL seems much more sensible than pushing millions of raw points into the browser.

2. it's significantly faster than existing Python charting libraries for real-time updates

3. I can imagine this useful to 'compress' gigabytes of data onto a 2d canvas quickly.

10. looks like assembler and more complicated

11. does make a difference when rendering on mobile and embedded devices with limited CPU

12. This is awesome, can easily see this becoming a standard library.

13. I like the XY language, what do you think?
