I used plotly extensively for a year. I enjoyed their python API, but the product side is really bad. I was paying for the corporate subscription and without a single email or anything they removed chat support from my subscription. When I tried receiving chat support one day, the operator told me my subscription no longer had that feature and when asked why this wasn’t ever communicated to me I was left with silence. Really awful customer support, and sneaky little usage features that make the product ultimately not worth it. I moved on to vega.js and it has been so much nicer in so many ways. Sorry to divert from OP so much, but plotly started out as the type of dataviz solution i was looking for and morphed into a misdirected, poorly run business seemingly more focused on competing in the BI space than doing what they were originally good at. Too bad.
