Readme for ihaskell-hvega-

[back to package description]


View Vega-Lite visualizations created by the hvega package in IHaskell notebooks.

When used with Jupyter notebooks it relies on Vega-Embed to do the hard work of parsing and displaying the Vega Lite specification.

If run in a Jupyter Lab then the native Vega support is used for displaying the Vega Lite specifications. I recommend using Tweag I/O's jupyterWith environment to set this up, and have a rudimentary shell.nix example in the notebooks directory.

This code is released under the BSD3 license.

Current status

If your visualization uses anything more modern than version 2 of the Vega-Lite specification (and possibly even version 2 features) then there is a good chance that it will not display correctly in IHaskell. This can differ depending on whether you are using the notebook or lab interface.

For the lab interface I am waiting for support for custom mime-types to be released (it is in the master branch of IHaskell). For the notebook interface I gave up on trying to work through the JavaScript issues I came across.
