This example displays a timeline of articles about Donald Trump, plotting each article as a point based on its modification date and allowing the user to aggregate the data by time intervals from seconds to years. It uses the d3-milestones library to render the timeline, with a dropdown menu in the HTML form controlling the aggregation granularity. The bundled JavaScript (bundle.js) supplies the article data, which includes titles, URLs, timestamps, and text snippets, and the visualization updates to reflect the selected time grouping.
