Making a Bar Chart
This bar chart displays weekly PM2.5 air quality levels in midtown Manhattan from February to May 2020, showing a general decline during the early COVID-19 outbreak, with data sourced from the NYC government website. Rendered as an SVG using D3 v5, the visualization employs `csv` to load data, `scaleLinear` for the x-axis, `scaleBand` for the y-axis dates, and `axisLeft`/`axisBottom` for axes. Bars are drawn with `rect` elements, while a light-blue background and lavender fills enhance readability.
