Creating custom chart types in Python

Hi !
I perform n simulations of operations planning. I can plot a gantt chart for each simulation, but I am interested in visualising the variability of the whole simulation set : I want a Gantt visualisation which includes information (mean, quantiles) about:

  • the distribution of starting dates
  • the distribution of ending dates

I would like to create a specific chart type derived from both a Gantt chart AND boxplots, and I would like to know if I can create this kind of custom chart types in Python or if I also need to dive into the plotly.js library ?
Thanks :slight_smile:
