{"version":"1.0","type":"rich","title":"Smoothed Daily Coronavirus Deaths Line Chart","description":"This chart plots smoothed daily coronavirus deaths over time for the top 50 countries by cumulative deaths, using a logarithmic y-axis to reveal relative trends across widely varying scales. The React app renders SVG lines with D3 scales and generators, while a D3-Delaunay Voronoi overlay enables hover interaction, highlighting the nearest data point and its corresponding country line with a tooltip. Data comes from the Johns Hopkins COVID-19 dataset, and daily values are smoothed via repeated averaging (15 iterations) before plotting.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/14bdac88ebf747c2b8a9a919bbe0a831?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
