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.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.

Data analysis

The visualization displays survey data from a class, plotting each student’s programming skills against their visualization skills in a scatter plot, while a bar chart shows their average rating across all skills. The bar chart is grouped by hobbies, and clicking a bar or circle highlights the corresponding student in both views. The code uses D3’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to build the charts, with `scaleOrdinal` for categorical colors. Data is loaded from a CSV file and rendered as SVGs.

Fork of Making a Bar Chart 3

This bar chart visualizes student test marks, with each bar’s length representing a score from 1 to 100. Built with D3 v5, it uses `d3.scaleLinear` for the x-axis, `d3.scaleBand` for categorical student labels, and `d3.axisBottom` with a custom tick formatter that abbreviates numbers. The SVG renders steel-blue rectangles, and the chart includes axis labels and a title. Data is loaded from a CSV and multiplied by 1,000 during preprocessing.

Testing D3

This visualization displays survey responses from students, showing each participant’s self-assessed collaboration skill as a horizontal bar chart. The bars are sorted in descending order by collaboration score, with aliases displayed along the vertical axis. Built with React and D3 v7, the example uses `d3.csv` to load data from a CSV file, and `scaleBand` and `scaleLinear` to map aliases and collaboration values to screen coordinates. The SVG rendering updates dynamically as the data loads, with a loading message shown initially.

Dendrogram + Grouped Horizontal Bar Chart

A hierarchical dendrogram combines with a grouped horizontal bar chart to display nested skill categories and proficiency levels. Each leaf node is paired with an animated, color-coded bar whose length encodes a numeric skill value (0–5), while internal nodes show category labels. The visualization uses D3 v4 with SVG and a custom tree layout, positioning bars adjacent to leaf nodes and applying distinct colors per skill. Subtle hover-free transitions animate bar widths on load, and dashed grid lines plus a custom top axis with qualitative labels ("Basic 1.0" through "Guru 5.0") enhance readability. The design adapts Mike Bostock's dendrogram concept by integrating grouped horizontal bars directly at the leaf tips, preserving hierarchical clarity while adding quantitative detail.

D3: Linked charts

A bar chart displays student grades from a dataset of student IDs and numeric grade values, with each bar representing a student. The visualization uses linked charts to show grades and allows sorting by ascending or descending order. Built with D3.js, it uses SVG rendering with animated bar transitions and axes. The bars are color-coded using hue and saturation, and hovering highlights individual bars to reveal exact grade labels. The data appears to be sample grade records with student IDs, and the chart is designed to compare grade distributions across students.

Demo Bar Chart with IT-Skill Data

This example presents a static bar chart of IT-skill data, organized by categorical skill names and their associated values. The visualization relies on a minimal HTML structure that loads the D3.js v6 library from a Content Delivery Network and executes a pre-compiled JavaScript bundle. The core rendering is driven by the D3 `scaleBand` and `scaleLinear` APIs to map data to horizontal bar lengths, while the `d3.csv` or similar data-loading mechanism is not explicitly shown, as the source data is embedded in the pre-built bundle. The chart focuses on clear categorical comparison through simple, unadorned bars.

Dendrogram + Grouped Horizontal Bar Chart

This visualization combines a dendrogram with grouped horizontal bar charts, mapping skill categories and subcategories to hierarchical tree branches while bar lengths indicate proficiency levels. The chart is rendered in SVG with a custom clustering layout and stratify function, using animated transitions to grow the bars when the page loads. Leaf nodes display colored rectangles with labels, while internal nodes show category names. The x-axis uses tick formatting to convert numeric values into experience labels like "Basic" through "Guru." The data comes from a CSV file containing skill names, numerical values, and color assignments, with the visualization based on Mike Bostock’s original dendrogram example.
