A grouped bar chart compares housing market metrics between March 2024 and March 2025, showing absolute values for six categories alongside color-coded percentage changes. The d3.scaleBand and d3.scaleLinear APIs position bars and axes, while value labels format prices with dollar signs and mortgage rates with percent symbols. A legend distinguishes the two years, and positive or negative trends appear as green or red arrows using SVG text elements. The chart includes title, subtitle, and source attribution within the SVG canvas.
