Pyground is a Python data playground that runs in your browser using Pyodide.
It allows importing a CSV file into a Python editor where it can be freely manipulated using common libraries. A Python editor that outputs a figure to a canvas is also provided. Dates in the document are converted to native Python DateTime objects so that they can be easily manipulated/plotted.
The app is entirely static, never stores your data or sends it anywhere and can be self-hosted anywhere.
A live version is deployed at https://pyground.vercel.app
- CSV file
- GraphJSON: any collection, any date range.
With Vercel:
Pyground is written in NextJS with all pages able to be rendered as static HTML. See NextJS docs for other deployment options

Python runs in the browser using Pyodide so their limitations apply. See in particular https://pyodide.org/en/stable/usage/wasm-constraints.html
-
The matplotlib render doesn't work in Safari, and that editor is therefore hidden. This includes all iOS browsers. See https://github.com/pyodide/pyodide/issues/1921
-
Your data is loaded in the browser, so the supported size will depend on your machine. You can almost certainly find a CSV file that's too big!
-
Currently only packages built in Pyodide are supported, and they're automatically imported when used. There's not yet any support for loading other packages.
