This example reproduces a Sol LeWitt art piece using React and D3. The visualization generates geometric wall drawings according to the artist’s conceptual rules, displaying the resulting patterns on a canvas. The code imports React 18 and D3 v7, though the commented-out script tags suggest the D3 library may be conditionally included. The React component `ShoppingList` renders a simple list, but the primary focus is the algorithmic drawing derived from LeWitt’s instructions, demonstrating how programming can emulate generative art.
