This example shows the most common W3C validation errors, ranked by frequency, using a horizontal bar chart. A gray bar represents each error’s count, and hovering highlights it in steelblue while the error message is displayed to its left. The data comes from a JSON file, loaded with `d3.json`, and the chart is built with D3 v3’s ordinal scale and SVG. The bars are drawn as `rect` elements, with axes using `d3.svg.axis` and a linear scale for the value domain.

AI-generated description

Source: W3CLove.

Pie charts are intended to show how one value compares to the whole. Since validation errors are not mutually exclusive (a single page can fail validation for multiple reasons), and the top 10 (or 100) reasons constitute an arbitrary whole, a bar chart is more suitable.

Bar Graph Vizualization

This bar chart visualizes the distribution of CSS levels across a dataset of colors, showing how many colors correspond to each specification level. The chart uses a vertical bar layout with hover effects that change bar color from steelblue to orange. Built with D3 v7, the visualization loads CSV data from a GitHub gist, aggregates counts with `d3.rollup`, and renders the chart as an SVG using `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis. Axis labels and rotated x-axis tick text clarify the categorical and numeric values.

51. D3 Bar Chart

This is a simple D3.js bar chart that visualizes a numeric dataset of 20 values, displaying each value as a rectangle scaled in height and colored in varying shades of blue. The chart uses an SVG element sized 500 by 100 pixels, with rectangles positioned horizontally and vertically scaled by a factor of four. Each bar is labeled with its corresponding number, rendered in white text. The example demonstrates basic D3 v4.5.0 APIs including `d3.select`, `svg.selectAll`, `.data()`, `.enter()`, and `.attr()`, with a static dataset defined as an array of integers.

Bar Chart

This bar chart displays compliance rates for the years 2010 through 2014, with the most recent year highlighted in brown. The visualization uses D3.js to load and parse frequency data, with ordinal and linear scales mapping years and compliance values to positions. Axes are rendered using d3.svg.axis, while d3.max computes the y-domain. The SVG output employs conventional margins and interactive hover styling, though the displayed data originates from a small inline array rather than the referenced TSV file.

Bar chart from external JSON file

This bar chart displays the frequency of each letter of the alphabet, using data loaded from an external JSON file. The visualization uses D3 v3 to create an SVG, with an ordinal x-axis for letters and a linear y-axis for frequency values. The bars are rendered as rectangles with a steelblue fill that turns brown on hover. The chart includes rotated x-axis labels and a y-axis labeled "Frequency," with data explicitly parsed from the JSON structure before scaling and rendering.

Data Visualization Module 3 - Bar Chart

This example displays a simple horizontal bar chart of a static JavaScript array of numeric values. Each value is represented by a steelblue rectangle, with the bar width proportional to the number and the numeric label printed at its end. The code uses D3 v3’s `d3.select` and `data` binding to append `div` elements, and applies a linear scale (`d3.scale.linear`) to map the data domain to pixel widths up to 420 pixels. All styling is done via inline CSS on the divs.

bar chart

This example shows a small, static bar chart of five categorical values, with each bar colored individually and labeled A through E. The chart displays the data using SVG rectangles, with linear and ordinal scales mapping the values to positions and heights. The code uses d3.js version 3.5, specifically d3.scale.linear and d3.scale.ordinal, along with d3.svg.axis for the x and y axes. The data is hard-coded in the script and rendered on a light grey canvas with margins applied via a group transform.

Bar Chart IIIa

This example shows a simple SVG bar chart of letter frequencies, with steel-blue bars and white value labels. Each bar’s height corresponds to a data point from a tab-separated `data.tsv` file, and the chart is sized to 960 by 500 pixels. The code uses d3.v3’s `d3.scale.linear`, `d3.tsv`, and data joins via `selectAll`, `enter`, and `append` to create `g`, `rect`, and `text` elements, with the scale mapping values to pixel heights.

Bar chart

A bar chart displays categorical values with six colored, semi-transparent rectangles. The visualization maps lettered categories (A through F) to numeric values, with axes labeled and gridlines rendered via D3's SVG axis API. It uses `d3.scale.ordinal` for the x-axis bands and `d3.scale.linear` for the y-axis range, while `d3.svg.axis` generates the ticks. Rectangles are appended and styled with `d3.scale.category10` colors, and the data comes from an inline array of objects with `x` and `y` properties.
