A prototype visualization displays a log-scaled vertical axis of Fire Weather Index (FWI) values against a categorical band axis, plotting three risk-area data points. The SVG chart uses d3.scaleBand, d3.scaleLog, and D3 axis components to render the pointer and arrow elements, with data drawn from a hardcoded array. A static arrow is appended as a separate SVG element. The layout divides the screen into three bordered columns for slider, chart, and bubble sections, though only the chart area is populated with visible elements.
