This example demonstrates various D3.js v5 scale and shape techniques using SVG rendering. It creates a chart with ordinal scales mapping 30 data points to point and band positions, displaying symbols and colored rectangles with d3.schemeCategory10 and schemeSet1-3. The visualization also plots the Weierstrass function using linear, identity, power, and log scales with d3.line paths. Additional elements include sine wave paths, areas with curve interpolation, arcs using d3.arc, and custom symbol shapes.
