{"version":"1.0","type":"rich","title":"Arcs and Lines practice","description":"This example visualizes country ruling party timelines using a React and D3 v5 stack. It fetches a CSV dataset and renders two horizontal lines representing different timeline tracks, with a gray sub-line and a black main line. The code leverages D3’s `csv`, `scaleLinear`, `arc`, and `line` utilities, though the current implementation focuses on line elements and an arc path. The SVG output is managed through React’s `useState` and `ReactDOM.render`, displaying loading states until data is fetched. The project demonstrates basic data loading and geometric shape composition within a React component structure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9a183ba29b1f4b9b84d85c3224dabf62?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
