Population and age

This visualization shows the U.S. population distribution across age groups from 2010 to 2019, using a slider to animate between years. It renders an SVG bar chart with D3 v4, where each bar’s height and color encode population size via `d3.scaleLinear` and `d3.scaleQuantile`. Transitions smoothly update bars and axes over two seconds. Data is loaded from ten CSV files using `d3.queue` and `d3.csv`. The code relies on D3’s `scaleBand`, `axisBottom`, `axisLeft`, and `transition` APIs.

Document

This interactive bar chart shows monthly values for a selected year, with a slider controlling the year from 2009 to 2014 and a smooth 2-second transition animating the bars to their new heights and colors. The visualization uses D3 v4 with a band scale for months, a linear scale for values, and a quantile color scale to encode magnitude. Data is loaded from six CSV files using d3.queue, and the chart updates by merging entering and existing SVG rect elements via `selection.merge` and applying axis transitions.

Population and age

An interactive bar chart displays population distribution across age groups for selected years, with a slider controlling the year from 2015 to 2019. The visualization uses D3 v4’s `scaleBand`, `scaleLinear`, and `scaleQuantile` for positioning and color encoding, with SVG rectangles animated via `transition`. Data is loaded from CSV files using `d3.queue` and `d3.csv`, while React state is not actually implemented despite the framework metadata.

Fork of Rendering Data with React & D3

This visualization displays all CSS named colors as equal-sized slices of a circular pie chart, using each color’s RGB hex value to fill its corresponding arc. The chart fills the entire frame because the pie radius is set to the SVG width. The example loads its data from a remote CSV file using D3’s `csv` utility, then uses React’s `useState` and `useEffect` to fetch and store that data. Rendering combines React components with D3’s `pie` and `arc` functions to generate SVG path elements.

Vega-Lite API Template

This bar chart displays population by country from a 2015 dataset, using Vega-Lite’s API to build the visualization with horizontal bars sorted by value. The code loads CSV data via `d3.csv`, configures axes and styling through a custom config object, and renders SVG using vega-lite and vega-tooltip for interactive hover details. The example demonstrates programmatic chart construction and React state management for handling asynchronous data.

Loading Data with React & D3

This example demonstrates loading external data with React and D3, displaying a summary of the loaded CSV file as text. It uses the `useState` and `useEffect` hooks to manage asynchronous data loading, with `d3.csv` fetching a dataset of CSS named colors from a GitHub gist. While the data loads, the interface shows a "Loading..." message; once fetched, a custom message function reports the file size in kilobytes, the number of rows, and the column count. React renders the result inside a `<pre>` element, combining D3's data parsing with React's state management.

Loading and Parsing CSV Data

This example demonstrates how to load and parse a CSV dataset using D3.js v7, displaying file size, row count, and column count for the CSS Named Colors dataset. The page uses `d3.csv()` to asynchronously fetch the data from a GitHub Gist URL, then `d3.csvFormat()` calculates the formatted string length in kilobytes. The `d3.csv()` promise chain updates the HTML `<pre>` element with the computed statistics, showing parsed dataset dimensions without any visual chart. The code relies on D3’s data handling APIs rather than creating marks or encodings.

Fork of Smiley Face Part V

A yellow smiley face with black outlined eyes and a curved mouth is rendered as an SVG in a React application. The visualization splits the face into separate React components for the background circle, eyes, and mouth, using React Fragments to group elements. The mouth is generated with a d3 arc, and the layout uses computed dimensions to center the face within a 960 by 500 viewport.

Smile Part 1

A yellow smiley face is drawn centered in an SVG canvas, with black eyes and a curved mouth, all constructed from React components. The visualization uses D3’s `arc` generator to create the mouth’s path, while the face, eyes, and stroke are simple SVG circles. The entire face group is rotated 180 degrees to orient the smile upward, and the layout is fixed at 960 by 500 pixels with reusable React components for the background, eyes, and mouth.
