True.

Since I got introduced to this simple but effective visualization (in my 30s!), I tend to use it everywhere.

Out of the “chart generation” apps listed in the catalog, only Vizzlo seems to support it: https://vizzlo.com/create/waterfall-chart (and Tableau, I suppose, but IDK if I'd count this as a simple chart generator). I did not check the listed charting libraries.

In my experience, this is the go-to chart for understanding financial drivers at the senior leader/board level.

Even the popular plotting libraries in python don’t seem to have an easily configurable version. Recently tried plotly and found it plotting the categories in reverse order from the intuitive way you’d expect to see.

I’ve been meaning to script my own custom plot since Excel’s waterfalls are tedious to create and you don’t get enough control over the labeling.

It's super hard to put together because you have to first do a factor analysis to even decide what the component parts are. I've always brute forced it using the (admittedly difficult) Excel function and the underlying dataset is not pretty!
