This bar chart displays COVID-19 total cases per country, with countries listed on the y-axis and case counts on the x-axis. Each bar is filled with a purple-to-pink linear gradient, and the axis labels use a separate gradient for text styling. The visualization is built with D3 v6, using `scaleLinear` and `scaleBand` to map the data, which is loaded from a CSV file. The code customizes the axes and text appearance through CSS rules, including tick label colors and font sizes.
