This bar chart visualizes cancer deaths in the USA for 2019, comparing three cancer types: liver, kidney, and lip/oral cavity. The code loads CSV data from a GitHub gist using `d3.csv`, filters for USA and year 2019, and maps the selected values to a dataset. It uses `d3.scaleBand` and `d3.scaleLinear` to position bars, with `d3.axisBottom` and `d3.axisLeft` for axes. The SVG rendering includes rotated x-axis labels and a title, with bars filled with steelblue.
