Basic data visualization features missing

[Anoop-Variyan]

Currently, the tool doesn't provide any data visualization possibilities. Basic data visualization functionalities within the results tab could be very useful for users so that they do not have to load the data into other tools for simple data visualization requirements.
E.g. Tables and charts (pie, bar, area, line, map etc).

I have tried some solutions for this, but providing a decent graph designer that runs purely on the browser does not produce acceptable results. Specifically, have tried Perspective.js for this but I did not manage to get results that I could call useful at an acceptable quality level in terms of presentation in the finite amount of time i dedicated to this. If you want I can provide a version of the app that has embedded Perspective.js charts so that you can experiment with it and evaluate it.

In general adding such a feature starts going beyond the initial scope and purpose of this site, and producing a decent result requires effort that is not justified by our goals. Having said that, it is a feature that we can consider for a future version and you are welcome to experiment with it and provide specific suggestions.

I also suggest considering providing Jupiter notebooks with graphs that are based on the queries in the query library. These we can easily integrate as demos linked to the query library examples and we can get pretty decent results under the controlled environment of python over specific SPARQL queries from the library.
