Choose dataviz template

Thank you Mathieu for your awesome work. Would it be possible to choose the dataviz template in Gephisto ? For instance, I've 2 datasets that I would like to visualize and compare to, but when I upload both files in Gephisto it's almost impossible to get similar dataviz.

Thank you.

No files, tests, or entry points are named. Start by tracing how Gephisto uploads datasets and selects or generates dataviz templates, then clarify which template choices and comparison behavior are required. Done should mean users can choose a template and obtain comparable visualizations for multiple uploaded datasets.
