{"version":"1.0","type":"rich","title":"Smoothed Line Chart","description":"Smoothed line chart comparing daily COVID-19 deaths across multiple countries, displayed on a logarithmic y-axis. The visualization uses a Gaussian kernel blur to smooth noisy daily counts, revealing underlying trends. Built with React and D3 v5, it employs `scaleTime`, `scaleLog`, and a custom `line` generator, with a D3 Delaunay Voronoi overlay for hover interactions. Hovering a point highlights the corresponding country’s full trajectory and displays a tooltip with the date and total death count. 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/949e4e1d874240b789bc05716e3a2ca7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
