Zoomable Timeline
This zoomable timeline visualizes time-series data across multiple scales, allowing users to explore yearly, weekly, and daily granularities. Built with D3 version 6, it uses axis utilities like `d3.axisTop` and `d3.utcTime` intervals to dynamically adjust tick density based on zoom level. The example provides a reset button and a slider to control the number of years displayed, with the SVG chart updating through a custom timeline function that manages grid lines and formatted labels.
