This visualization displays monthly unemployment rates across Canadian provinces, using a grid of colored tiles to represent rate changes. Each tile’s color encodes the magnitude of change, from green (negative) to white (neutral) to magenta (positive), while vertical positioning reflects each province’s rank. The chart uses a D3.js v6 SVG layout with `d3.scaleBand` for axes, `d3.scaleSequential` for color interpolation, and interactive tooltips. Data is loaded from a CSV file containing month, province, amount, changed, and rank fields.
