Since Altair 5.3, the functionality of Altair Viewer is now available in Altair via the vl-convert package instead. See the docs on how to use the browser renderer to display charts via .show(), and the PR vega/altair#3379 for more details.

We are going to archive this repo, so I'm closing all the open issues and PRs before doing so. Try out the new options for rendering charts mentioned above and if you run into issues, please open an issue directly in the altair or vl-convert repo.
