Sylvain Lesage’s cool interactive explainer on visualizing extreme row counts—think billions—inside the browser. His technical deep dive explains how the open-source library HighTable works around scrollbar limits by:

- Lazy loading - Virtual scrolling (allows millions of rows) - "Infinite Pixel Technique" (allows billions of rows)

Hyperparam sponsored Sylvain’s work as part of our broader effort to invest in open-source infrastructure and get ahead of the data-scale problems that are emerging with LLMs. With a regular table, you can view thousands of rows, but the browser breaks pretty quickly. We created HighTable with virtual scroll so you can see millions of rows, but that still wasn’t enough for massive unstructured datasets. What Sylvain has built virtualizes the virtual scroll so you can literally view billions of rows—all inside the browser. His write-up goes deep into the mechanics of building a ridiculously large-scale table component in react.
