You spend hours tweaking axis limits, hiding grids, calculating exact tangency points, and trying to align multiple subplots.</p> <p>I got tired of doing this manually for my teaching materials, so I built <code>econ-viz</code>. </p> <p>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:</p> <h4> Elegant Multi-Panel Layouts </h4> <p>I’ve introduced a new <code>Figure</code> 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 <code>matplotlib.gridspec</code>.</p> <h4> The <code>DemandDiagram</code> </h4> <p>Showing the derivation of the Marshallian demand curve requires stacking the utility space directly above the price-quantity space. <code>econ-viz</code> now perfectly aligns the axes and automatically links the tangency points on the indifference curves to the points on the demand curve below.</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fi71paxzn1x42pt40bjw3.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fi71paxzn1x42pt40bjw3.png" alt=" " width="800" height="1652"></a></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Flnbvk4xjbtiqijoq7u6i.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Flnbvk4xjbtiqijoq7u6i.png" alt=" " width="800" height="1652"></a></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F5a2k68jnwq26scnc6z35.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F5a2k68jnwq26scnc6z35.png" alt=" " width="800" height="1652"></a></p> <h4> Analytical Tools </h4> <p>It doesn't just draw; it solves. I've added new features to support your analysis:</p> <ul> <li> <code>solution_tex</code>: Outputs the optimal solutions in clean LaTeX format.</li> <li> <code>comparative_statics</code>: Easily perform and visualize comparative statics.</li> <li> <code>slutsky_matrix</code>: Computes the Slutsky matrix for deeper demand analysis.</li> </ul> <h3> The Mission </h3> <p>My goal with this open-source project is simple: <strong>Economists, educators, and students should spend their time analyzing models, not hand-coding chart coordinates.</strong></p> <p>If you are teaching microeconomics, writing notes, or publishing papers, give it a try!</p> <p>📖 <strong>Documentation:</strong> <a href="//econ-viz.org">econ-viz.org</a><br> 🐙 <strong>GitHub Repo:</strong> <a href="https://github.com/EconViz/econ-viz" rel="noopener noreferrer">github.com/EconViz/econ-viz</a></p> <p>If you have a specific economics chart that is currently a nightmare to draw, drop a comment below or open an issue on GitHub! Happy plotting!</p> python matplotlib productivity startup Anthony Sung Fri, 20 Mar 2026 04:00:50 +0000 https://dev.to/yueswater/d-41k https://dev.to/yueswater/d-41k <p>d</p> d
