As the title says, which programming language would you agree had the best libraries for visualisation (graphs, 3d models, charts, networks, animations, etc)?
Prefer languages with libraries that have more visulatizaton features than say, ease of using the libraries.
js has access to Apache echarts, which has a lot of diagrams and good api and doc with example
Python has access to matplotlib, plotly and more.
Both have the advantage of good support for secondary feature for data gathering and ui.
