This example displays the twelve month abbreviations in a horizontal row across an SVG canvas, demonstrating how D3 scales map data values to visual properties. Using the D3 v7 library, it applies a linear scale (`d3.scaleLinear`) to position each text label along the x-axis, while an ordinal scale (`d3.scaleOrdinal`) assigns a fill color of black to the first month and grey to the remaining ones. The labels are rendered as SVG text elements using D3's selection and join methods.
