A few years ago I wrote Multi-parameter Jupyter notebook interaction about a Jupyter notebook. It worked at the time, but when I dusted it off recently, it didn’t. I’ve renovated it and cleaned it up a little, and now it works again.

It’s a Jupyter notebook with a simulation of late-career money flows to figure out possibilities for retirement. It uses widgets to give you sliders to adjust parameters to see how the outcome changes. It also lets you pick one of the parameters to auto-plot with multiple values, which gives a more visceral way to understand the effect different variables have.

You can get the notebook itself if you like.
