This interactive visualization examines Earth’s accelerating rotation through three linked charts: a scatterplot of record-breaking short days, a bar chart of leap seconds by decade with a predicted negative value, and a panel of factors influencing rotation speed. Built with React 19 and D3 v7, it uses `scaleTime`, `scaleBand`, and `scaleLinear` for axes, and `ResizeObserver` for responsive rendering. Hover and click interactions allow users to select data points and bars, with state managed via React hooks. Data comes from the embedded `earthRotationData.js` file, reflecting recent astronomical measurements.
