widget dag

This article introduces WidgetDAG, a new tool that allows hosting interactive notebooks as directed acyclic graphs (DAGs) on static blogs. It leverages marimo, wigglystuff, and marimo-mdx to embed live widgets like a paint canvas and convolution kernels, with automatic dependency tracking. The implementation uses Pyodide/WASM to run Python in the browser, enabling dynamic data flow visualization without a server. The post includes code examples and demonstrates how to create a graph widget that orders variable execution based on marimo's internal tracking, making it suitable for technical tutorials and interactive demos on static sites.
