{"version":"1.0","type":"rich","title":"Line graph","description":"A line graph displays daily high stock prices for CS Bank over time, with a red-to-green vertical gradient applied to the stroke. The chart includes labeled axes, a title, and a hover interaction that reveals the exact price at any point via a movable circle and text label. Built with React and D3.js v4, it loads CSV data from a GitHub gist, parses dates with `d3.timeParse`, and renders the line using `d3.line` with a `linearGradient` fill. Interactive tooltips rely on `d3.bisector` for nearest-date lookup.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2be3db6ad116436e9653da44e406e9f5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
