This diverging bar chart visualizes Sweden’s repo rate from 2010 to 2024, with positive rates in blue and negative rates in red, centered around a zero baseline. Using D3 v7, it loads CSV data via `d3.csv`, maps years to a band scale and percentages to a linear scale, and renders SVG rectangles with a color scale. The chart includes axes, labels, and a legend built with `d3.legendColor`. The data comes from a Gist, and the design effectively highlights periods of negative interest rates.
