Daily Coronavirus Confirmed Cases of California and New York State by County
This chart displays the daily confirmed COVID-19 cases for counties in California and New York, plotting each county’s time series on a logarithmic scale. A Voronoi overlay, created with `d3.Delaunay`, enables hover interactions, revealing a tooltip with the total confirmed cases up to that date. The visualization is built with React and D3 v6, using `scaleTime` and `scaleLog` for the axes, and renders as an SVG using `line` and `axisBottom`. Data is sourced from the Johns Hopkins Coronavirus dataset.
