{"version":"1.0","type":"rich","title":"Smoothed Line Chart","description":"This smoothed line chart tracks daily COVID-19 death counts over time for the top 50 countries, using a log-scaled y-axis and data from the Johns Hopkins Coronavirus Dataset. The chart applies a Gaussian blur to smooth the raw daily values, rendering each country as a line in an SVG. Hovering over any point triggers a Voronoi overlay built with `d3-delaunay`, highlighting the corresponding country's line and displaying a tooltip with the exact date, total deaths, and country name. The visualization uses React with D3 v5 components like `scaleLog`, `scaleTime`, and `axisBottom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/28261ccfe9dd43c096e90c4872eefd8c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
