Vis: Histogram visualization

[puehringer]

Short description

Currently, we don't have a visualization for histograms, similar to https://plotly.com/javascript/histograms/ (which may even be used as implementation and we just do the wrapper). We have the bar chart, but that is working for categorical columns only.

User stories

• I want to look at aggregated visualizations of my (numerical) data
• I want to create stacked/overlaid histograms from categorical columns
• I want that selections are synced the same they are synced in the bar chart (i.e. bars depicting subset of selected data)
