Interactive plots

[sbrugman]

The generated reports currently contain static images, which is problematic since (1) the (base64) encoded image make that the reports are large (multiple MBs) and (2) there is no interactivity, so for instance it’s not possible to read the maximum value from a diagram. Both can be tackled by implementing another plotting library (such as Plotly or Altair) that renders the plots client-side. The challenge lies in serving the report and data together efficiently.
