{"version":"1.0","type":"rich","title":"Fork of React + D3 Viz Starter","description":"A timeline chart displays dated events with circular markers, bold titles above and descriptions below a centered time axis. The example plots policy accomplishments using D3 v6 scales and axes, with React 16 components managing the SVG container and margin layout. Data flows from a static JavaScript array through `TimelineChart`, which calls the `Timeline` visualization function to render circles, labels, and the bottom axis via `d3.axisBottom`. A reusable `VizContainer` component wraps the SVG group, optionally showing margin guides via a `showMargins` prop.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6b2c03f233c14d568f3d0412b753485c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
