This diverging bar chart displays average January 2016 temperatures across Alaska cities, with each bar extending left or right from a central zero line based on temperature. The visualization uses a red-blue diverging color scale to emphasize cold versus warm readings. The code employs D3 v7’s `scaleLinear`, `scaleBand`, and `scaleSequential` with the `d3.interpolateRdBu` interpolator, while rendering bars as SVG rectangles. Data is loaded from a CSV via `d3.csv`, and the legend is generated using the d3-legend library’s `legendColor` function.
