{"version":"1.0","type":"rich","title":"Line Chart","description":"A line chart displays smoothed daily COVID-19 death counts over time for the top 50 countries, colored by data from the Johns Hopkins Coronavirus Dataset. It uses a logarithmic y-scale and a Gaussian kernel blur to smooth the time series. Hovering over a Voronoi overlay, generated with `d3.Delaunay`, highlights the nearest data point and illuminates the corresponding country’s line, while a tooltip shows the country, date, and approximate death total. The chart is built with React and D3 v5, rendering SVG paths via `d3.line` and axes with `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c5189398f5a3429eb639d4444bf0c8f4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
