Local Data processing

[parasjindal-tf]

Hi Redash community, I have a requirement to process data locally before visualizing it.

There is a certain type of logic which is not very straightforward to write in query language. But if I fetch the required data from DB, and have an option to pre process it before rendering using local js scripts, it would be very helpful.

I have explored the option of custom charts, where I can write custom js functions, but confined to use Plotly. If that can be extended to just return the processed data and can use Redash native charts as it is, it should solve the purpose I believe.

Do you folks have this type of requirement, or any other alternatives to solve this kind of problem?
