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.

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.

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 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.

D3 tutorials

This example demonstrates a basic bar chart visualization. It shows a dataset of seven numeric values, each rendered as a fixed-width blue bar whose height corresponds to the value. The chart is built using D3.js methods to select the HTML body, append a `div` for each data point, and apply the CSS class `bar`. The bar heights are set inline using a JavaScript arrow function, and the initial styling is defined within a CSS style block. The code relies on `d3.select`, `d3.selectAll`, `.data`, `.enter`, `.append`, `.attr`, and `.style` to construct the visualization. The data is hardcoded as an array.

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.

D3 testing2

A D3.js bar chart visualizes a single student’s self-assessed skills across five categories: programming, computers, art, communication, and collaboration. Each category is rendered as a fixed-width rectangle, with bar heights scaled by multiplying the numerical skill value by ten. The chart uses SVG rectangles appended directly to a hardcoded, static data object, with no axes or scales defined. Interactive tooltips appear on hover, implemented via D3 mouseover, mousemove, and mouseleave event handlers that dynamically update an HTML div’s opacity and position.

D3: Drawing a Bar Chart

This example demonstrates a basic bar chart built with D3 v7 in an SVG container, visualizing an array of 20 numeric values. The bars grow downward from the top of a 500×100 pixel canvas, with each bar’s height proportional to its data value multiplied by 4, and its fill color transitioning from dark to lighter blue based on the data. The chart also overlays each bar with white, 11px sans-serif text labels showing the exact data values, centered horizontally within each bar. The code uses `d3.select` to append SVG elements and the data-join pattern with `.enter()` to create rectangles and text nodes.
