This example demonstrates how to control the placement of tick marks on a chart axis using the D3.js library. It shows a single horizontal axis with four specified tick values (0, 50, 60, 100) rendered along a linear scale that maps the domain 0–100 to a pixel range of 0–400. The code constructs the axis using `d3.scale.linear()`, `d3.svg.axis()`, and the `tickValues()` method, then appends it to an SVG element. The axis is positioned via a translate transform, with CSS styling providing black strokes for the axis line and tick marks.
