This example visualizes a historical timeline of Israel, organized into three major eras with matplotlib-colored event markers plotted along a horizontal axis. It uses D3.js v7 to render SVG elements, including clickable era groups, event circles, and axis labels. The code employs helper functions to parse date strings into numeric x-coordinates, handles date ranges, and includes a tooltip feature for hover details, with an additional zoom function for events around the year 2000.
