{"version":"1.0","type":"rich","title":"Smoothed Line Chart","description":"This example shows smoothed daily death counts over time for the top 50 countries, using a log-scaled y-axis. Each country is rendered as a line, and hovering over any data point highlights the corresponding line and displays a tooltip with the country name, date, and total deaths. The data comes from the Johns Hopkins COVID-19 dataset. The visualization uses React with D3 v5 for scaling, line generation, and axis construction, while a Voronoi overlay built with `d3.delaunay` handles hover detection. The smoothing is applied via a Gaussian kernel blur.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2ecde54ee7ca4b6abccb8a4a9381d134?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
