{"version":"1.0","type":"rich","title":"Coronavirus Line Chart With Margin Convention","description":"A line chart tracks cumulative global COVID-19 deaths over time using the Johns Hopkins dataset, with a red horizontal marker at one million deaths and a vertical “now” marker at the most recent date. The React component builds a time-scaled `d3.line` path within an SVG, applying explicit margin offsets to position axes. It uses `d3.scaleTime`, `d3.scaleLinear`, `d3.extent`, and `d3.max` to map data, while custom `XMarkerLine` and `YMarkerLine` components place annotation lines and labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0fc6670a5b504979b752014e90ecf69c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
