This visualization shows daily COVID-19 cases in New York City from late February to mid-May 2020, using vertical bars to represent case counts over time. The chart is rendered as an SVG using D3 v5, with a linear scale for cases and a band scale for dates. It employs `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` from the d3 module to construct the axes and bars. Data is loaded from a CSV file via `csv("data.csv")`, with hover effects changing bar color to orange. The underlying data appears to come from NYC Health data.
