svgsmith

Agent-native, self-verifying raster→SVG vectorizer + SVG→PNG (CLI + skill). Wraps VTracer/Potrace; auto-routes by image type, curve-smooths to editable SVG, self-verifies via re-rasterization. Agent-customizable flags (--detail, --solid-background, …) turn a user's plain request into the result.

pervect

Vectorization of persistence diagrams and approximate Wasserstein distance

datadez

Pandas dataframe easy inspection, filtering, transformation: Get label distribution metrics, visualize multilabel columns through Chord diagram, filter label occurring less than a threshold, one-liner text/monolabel/multilabel columns vectorization, and many more to come.
