{"version":"1.0","type":"rich","title":"COVID-19","description":"This interactive dashboard visualizes the daily progression of COVID-19 cases, deaths, and recoveries for a selected country in 2020. Using dropdown menus built with a custom reusable `dropdownMenu` function, viewers can switch between the three status metrics and any available country to update a line chart rendered as SVG paths. The code loads data from a CSV file containing daily province-level records, aggregates entries by country and date using `d3.nest` and `reduce`, and draws the time series with `d3.line`, `d3.scaleTime`, and `d3.scaleLinear`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/48b465bb0d4745ae89e84587bad51e23?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
