This example shows a bar chart built with D3.js version 5, where the vertical axis maps data values using a linear scale with rounded output coordinates. The chart’s height and width are read directly from the SVG element, and an array of ten generated data points is created using the d3.range function. The visualization is rendered as an SVG, with the y-axis scale defined through d3.scaleLinear and a d3.line object configured to position points based on the data values, though the actual bar drawing is not visible in the provided code.
