{"version":"1.0","type":"rich","title":"use the scaleLinear() to draw barchart2","description":"This example demonstrates how to draw a simple bar chart using D3.js version 5’s `scaleLinear()` function to map data values to pixel widths. A hardcoded array of five numeric values is transformed into green rectangular bars, each with a fixed height and spacing, rendered as SVG within a React-equipped HTML page. The code explicitly creates a linear scale with a domain from zero to the maximum data value and a range of 0 to 400 pixels, then applies that scale to each rectangle’s width attribute via D3’s data join and selection methods.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
