{"version":"1.0","type":"rich","title":"Coronavirus Basic Line Chart With Margins","description":"This example displays global COVID-19 death totals over time with a line chart, using a time-scaled x-axis and linear y-axis with margins. D3 v7’s `scaleTime`, `scaleLinear`, and `line` generators construct the SVG path, while `YMarkerLine` and `XMarkerLine` components overlay reference lines at 5 million deaths and the most recent date, respectively. Data loads from the Johns Hopkins CSSE CSV via `d3.csv` and `timeParse`. The React app computes daily global sums and renders the chart full-screen.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/85c858eb9e664e76852ffe7178bbfe5d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
