This example demonstrates SVG path drawing primitives by rendering a grid of vertical and horizontal lines using D3 v5. It creates a 10x5 lattice of green strokes on an SVG canvas with a viewBox of 100x50 units. The code uses `d3.select` to append the SVG element and `d3.range` to generate data arrays, then appends path elements whose `d` attribute strings are constructed with template literals for `M` (moveto), `V` (vertical line), and `H` (horizontal line) commands. The rendering relies entirely on SVG path syntax without additional geometry libraries.
