Three different ways to represent colo(u)r. Work in progress, inspired by an old post by Kat Zhang / The Poet Engineer.
Three scatterplots of colorful points. titles = ['Color Space', 'Text Space', 'Image Space'] subtitles = ['Embeddings of color features', 'Text embedding of color names', 'Image embeddings of color swatches']

I made this annotated scatter plot of 1 million FineWeb-Edu documents for @sashamtl.bsky.social's new TED talk.
Scatterplot of a document corpus with cluster information in the form of colors and cluster labels. Includes labels like computing, mental health, religion, etc.

When the fish left the river:
A four frame comic about the Cambodian genocide. In the first frame, a man can be seen from the back, looking at a window. The text reads: "I never ask my father about Cambodia." In the second frame, a silhouette of the father can be seen, screaming in his sleep, arms reaching into nothingness. The text reads: "What could he say, really, that he didn't already scream in his nightmares?". The third frame shows the father pondering on something, expression neutral. The text reads: But sometimes he would say "It's funny, when it happened, all the fish left the river. They never came back." . The fourth frame shows the father lowering his head, thinking. He says: "I guess they knew." The second page of the comic on the Cambodian genocide, and everything to come. The first frame shows the daughter, young, silent and unsure of what to say. The text reads: "I didn't say anything then." In the present, the daughter, now an adult, looks at the Seine in Paris. The text reads "But I often think of it now.". The daughter then crouches near the Seine to see if there are any fish left. She says: "Are you still here?".

Also really love how organic the plot looks with "inferno" (left) and "viridis" (right).

Thanks to @jamesabednar.bsky.social I realized I had used the wrong background color for the colormap I had chosen. This is another version of the plot (different embeddings) with the corrected background.
Correct version of the plot in the quoted post. Graph with an organic like structure of the BGP network.

Really cool new embeddings exploration tool by @domoritz.de and colleagues from Apple. Can't wait to build with this. Also includes a streamlit component and a Jupyter widget.

I recently used the @lichess.org puzzles dataset to experiment with chess position embeddings and visualize 4.5M starting positions. (hf.co/datasets/Lic...)
Scatterplot with 4.5M data points. Inferno colormap. Looks somewhat organic with neat clusters.

UMAP connectivity graphs—with edgehammer bundling—are always something to gaze at.

Revisiting John Williamson's prime factors plot with a few differences in implementation. I am using UMAP and Datashader to visualize the first million integers. Not quite there yet.
2d scatterplot in the viridis palette. Different blobs and clusters. Looks very starbursty in some places and very organic in others.

Code Dataset Visualization—11.66 million files from the Stack, a dataset sourced from permissively-licensed GitHub repositories spanning 86 programming languages (StarCoder languages subset).
Scatterplot of many points using a fire-theme palette on a black background. The points cluster in small groups. The general shape is circular, as is common of TSNE embeddings.
