uPlot is a small, fast, memory-efficient Canvas 2D charting library for time-series data, supporting lines, areas, OHLC, and bars. From a cold start it can render an interactive chart with 166,650 data points in about 25ms and then scale at roughly 100,000 points per millisecond for smoother interactions. At roughly 50 KB and MIT license, it emphasizes a lightweight footprint with top-tier zooming and cursor performance.
