{"version":"1.0","type":"rich","title":"Smoothed Daily Coronavirus Cases Line Chart","description":"A line chart visualizes daily confirmed coronavirus cases over time for the top 20 countries by cumulative cases, with each country's trajectory smoothed via 30 iterations of a repeated averaging blur technique on the `deathDaily` values. The display uses a logarithmic y-axis and an SVG rendering with React, employing `d3.scaleTime` and `d3.scaleLog` for axes and `d3.line` with monotone interpolation for paths. A Voronoi overlay from `d3-delaunay` enables hover interactions that highlight the active country’s line and show a tooltip with exact case totals and dates. Data comes from the Johns Hopkins Coronavirus dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7622b966e4034e61bd7706617b6c4708?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
