This contour plot visualizes a data surface through layered SVG paths and grouped rectangles, using filled shapes to represent different value bands. The visualization renders with React and SVG, employing path elements with complex cubic and quadratic Bézier curves to trace contour lines. A color scale ranges from dark purple through magenta and orange to pale yellow, with each colored region corresponding to a specific elevation range in the plotted dataset. The implementation uses direct SVG path data rather than a charting library, providing precise control over the geometric contour representation.
