This example shows a simple bar chart built with D3.js v7, displaying four individuals’ scores against a 100-point axis. Blue rectangles are positioned using a band scale for the x-axis and a linear scale for the y-axis. The code renders SVG elements via `d3.select` and `join`, with axes generated by `d3.axisBottom` and `d3.axisLeft`. Data is hardcoded as an array of objects, and the chart includes margins and a viewBox for responsive sizing.

Making a Bar Chart

This example displays a bar chart of four individuals’ scores, with blue bars representing values on a scale from 0 to 100. It uses D3 v7 to create an SVG graphic, employing the `d3.select` method to append the chart to the page, `d3.scaleBand` and `d3.scaleLinear` to map data to x and y coordinates, and the `join` operation to bind each data point to a rectangle element. The chart’s dimensions and margins are fixed, and the data is hard-coded in the script.

Making a Bar chart

This example shows a bar chart of four people’s scores using blue rectangles on an SVG canvas. The data is hard-coded as an array of objects with names and scores. The chart uses D3.js v7 to create band scales for the x-axis and linear scales for the y-axis, with a margin-defined layout. The code leverages D3’s `selectAll` and `join` operators to bind data to the rectangles, setting each bar’s position, height, and width based on the score values. The visualization is rendered as SVG without axes or labels, focusing only on the bar geometry.

Making a Bar Chart

This example shows a simple bar chart comparing the scores of four people—Simon, Mary, Jo, and Peter—on a scale from 0 to 100. It uses d3.scaleBand and d3.scaleLinear to map data to positions, with blue SVG rectangles drawn via d3.selectAll and data joins. The chart includes custom x and y axes built with d3.axisBottom and d3.axisLeft, labeled with names and numeric ticks. Rendering uses SVG within an 800-by-400 viewBox, with margins applied around the plot area.

D3.js Tutorial

This example shows a bar chart of test scores for seven people, sorted from highest to lowest score, with royal blue bars, labeled axes, and hover opacity feedback on each bar. The visualization uses D3.js v5 with an SVG rendering approach, creating scales via `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis. It appends rectangles bound to an array of name-score objects, calls `d3.axisBottom` and `d3.axisLeft` for the axes, and sorts the data with `d3.descending`. The chart is embedded in a basic HTML page with a centered title.

making a bar chart

This bar chart displays scores for four individuals, Simon, Mary, Jo, and Peter, using blue vertical bars on an SVG. The chart builds with D3 v7, using `d3.scaleBand` for the x-axis categories and `d3.scaleLinear` for the y-axis range from 0 to 100. Axes are rendered with `d3.axisBottom` and `d3.axisLeft`, with custom tick formatting for names. The hardcoded data is bound via `selectAll` and `join`, and the SVG includes a viewBox for responsive sizing.

Making a Bar Chart

This bar chart displays the scores of four individuals—Simon, Mary, Jo, and Peter—on a fixed scale from 0 to 100. Each name is plotted as a blue rectangle using D3.js v7, with the chart rendered in SVG within a React-free HTML page. The code constructs an SVG canvas with specified dimensions and margins, then uses d3.scaleBand to position bars along the x-axis and d3.scaleLinear for the y-axis. Rectangles are appended and sized via data joins, with heights calculated from the score values.

Making a Bar Chart

This example creates a static bar chart using D3 v7, displaying categorical data as vertical bars with labels. The visualization uses `d3.scaleBand` for the x-axis positioning and `d3.scaleLinear` for the y-axis scale, with bars rendered as styled SVG `rect` elements. The code employs `d3.max` to compute the domain, `d3.axisLeft` and `d3.axisBottom` to generate axes, and `d3.select` with data binding to append the shapes. A hardcoded local array provides the dataset.

D3.js Tutorial

This example shows a D3.js bar chart that displays the scores of seven individuals, sorted in descending order. The chart uses a band scale for the x-axis and a linear scale for the y-axis, with bars rendered as SVG rectangles that highlight on hover. The code calls on d3.scaleBand, d3.scaleLinear, d3.axisLeft, and d3.axisBottom to construct the axes and layout, while data is sorted with d3.descending before binding. The visualization is embedded in a minimal HTML page with D3 v5 loaded from a CDN.
