This visualization displays daily COVID-19 case counts in New York City as a bar chart, with tooltips that reveal the exact case number and date on hover. The bars turn orange when the mouse passes over them. The chart uses D3 v5’s `scaleBand` and `scaleLinear` for axes, and renders as SVG. Tooltip functionality is provided by the `d3-tip` library, which appears on mouseover and hides on mouseout. Data comes from the included `data.csv` file, which contains date, case, hospitalization, and death counts.
