I want to develop a web-based 'business intelligence' app to analyze and visualize data. CB Insights (https://cbinsights.com) comes very close to it. Some features are: visualize company information, add companies to a watch-list, send alerts etc.

For starters, I am looking for an efficient way to visualize time series, but I cannot find anything that seems to work for large amounts of data (up to one billion rows). At my company we have a data warehouse, with a star schema on top and Cognos, Pentaho etc. visualize the data.

Is there something similar for the web?

So far I have tried: * Django and Superset (https://superset.incubator.apache.org/): this works great but then my Superset-visualization is decoupled from Django and I cannot do anything with the data I visualize. * Django and Cubes-Framework (https://cubes.readthedocs.io/en/latest/#): This looks like a great solution but it is not fast (loading the same data in Superset, for instance, is instant, whereas it takes around ten seconds in Cubes)

What are some standard solutions for such applications?

Thanks!
