{"version":"1.0","type":"rich","title":"Coronavirus Line Chart with D3 Axis","description":"This chart visualizes global COVID-19 death totals over time using a line path, with a horizontal marker at the 1 million death threshold and a vertical marker at the most recent date. The React component uses D3 scales (scaleTime, scaleLinear) and a line generator to map the Johns Hopkins dataset, while custom XAxis and marker components render grid lines and labels. SVG output displays the path with a bold black stroke, styled tick marks, and formatted date labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/27ebc60c61c14645851ca6ffe98f5437?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
