I'm not sure what you mean by interactive data visualizations. But there are a bunch of companies and open source projects that have charts and you can interact with them:

* chartio (https://chartio.com) - commerical * looker (https://looker.com) - commerical * metabase (http://www.metabase.com/) - open source * http://fnordmetric.io/ - open source

There's a ton more that I haven't listed.
