{"version":"1.0","type":"rich","title":"tmp","description":"This example displays a line chart of COVID-19 daily new cases over time, with interactive data points. It uses D3 v6 to load CSV data from a local file, parse dates, and render the chart with axes, a line path, and circles for each data point. Hovering over a circle triggers a tooltip that shows the specific date and case count. The visualization is built with D3's `scaleTime`, `scaleLinear`, `line`, `axisBottom`, and `axisLeft` APIs, and rendered as SVG with a title header.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8d112046ad56426786deb2f1633d7073?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
