If you’ve ever tried to draw a simple microeconomics graph—say, an indifference curve tangent to a budget constraint—using raw Python or LaTeX, you know the struggle. You spend hours tweaking axis limits, hiding grids, calculating exact tangency points, and trying to align multiple subplots.
I got tired of doing this manually for my teaching materials, so I built econ-viz.
With our latest major update, it goes from being "a cool wrapper" to a "production-ready tool for economics lectures and papers." Here is how it solves the biggest headaches in drawing economics charts:
Elegant Multi-Panel Layouts
I’ve introduced a new Figure class that handles standard economic layouts out-of-the-box. Whether you need side-by-side, stacked, or 2x2 comparisons, you can generate them cleanly without fighting matplotlib.gridspec.
The DemandDiagram
Showing the derivation of the Marshallian demand curve requires stacking the utility space directly above the price-quantity space. econ-viz now perfectly aligns the axes and automatically links the tangency points on the indifference curves to the points on the demand curve below.
Analytical Tools
It doesn't just draw; it solves. I've added new features to support your analysis:
-
solution_tex: Outputs the optimal solutions in clean LaTeX format. -
comparative_statics: Easily perform and visualize comparative statics. -
slutsky_matrix: Computes the Slutsky matrix for deeper demand analysis.
The Mission
My goal with this open-source project is simple: Economists, educators, and students should spend their time analyzing models, not hand-coding chart coordinates.
If you are teaching microeconomics, writing notes, or publishing papers, give it a try!
