A smoothed multi-line chart compares daily COVID-19 deaths over time for the top 50 countries by cumulative deaths. The y-axis uses a logarithmic scale to accommodate wide value ranges, and the lines are smoothed via a repeated averaging technique. Built with React and D3 v5, the visualization uses a Voronoi overlay for hover detection to highlight a selected country's line and display a tooltip with details. Data is sourced from the Johns Hopkins Coronavirus dataset.
