{"version":"1.0","type":"rich","title":"Chart 1","description":"This visualization displays the progression of confirmed COVID-19 cases over time as a single orange line chart. The x-axis maps dates using `d3.scaleTime`, while the y-axis uses `d3.scaleLinear` to represent case counts. Data is loaded via `d3.csv` from a GitHub gist and parsed with `d3.timeParse`. The line is rendered with `d3.line`, and axes are drawn using `d3.axisBottom` and `d3.axisLeft`. The SVG structure is built with D3 v6, with explicit margins, axis labels, and a white background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f4a83ef5b3dd4feca846a113033a8d28?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
