This tool can be used to draw an interaction plot from a regression model.
It is in no way a replacement for tools such as Stata's
`margins`

/
`marginsplot`

or any of the various R packages (e.g.
**emmeans**,
**interactions**,
or **marginaleffects**),
but may be useful if using software that does not support easy generation
of such plots.

Currently this tool supports only continuous/continuous interactions (or binary, if you code it as 0/1), and only linear regression models. I hope to add support for categorical interactions as well as non-linear models.
