{"version":"1.0","type":"rich","title":"Coronavrius Line Chart with marker line","description":"A line chart tracks cumulative global COVID-19 deaths over time, using a black marker line to highlight the point where the death toll reaches three million. The visualization loads time-series data from the Johns Hopkins CSSE repository via `d3.csv`, transforms dates with `d3.timeParse`, and renders an SVG path generated with `d3.line`. Scales are created with `d3.scaleTime` and `d3.scaleLinear`, while React manages the component state and updates the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/da3ba69a3b8942888914951cf0eb514a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
