This interactive pie chart displays population data by age group, with each wedge rotating to the bottom when clicked. Built with D3 v4, the visualization uses `d3.pie` and `d3.arc` to generate SVG paths, while a `transition` on the containing `<g>` element rotates the entire chart so the selected wedge aligns with the bottom. Label text rotates in the opposite direction to stay upright, and clicks are handled via the `.on("click")` method. The data is hardcoded in the script, and the chart is styled with ordinal color scales for the seven age categories.

AI-generated description

This pie chart, based on Mike Bostock's example, rotates so that any clicked wedge well spin to the bottom. The text rotates in the opposite direction so that it remains upright.

Pie Chart

This pie chart displays the population distribution across seven age groups, from under five to 65 and over, with each slice labeled and colored distinctly. The visualization is built using D3 v4, leveraging d3-dsv to parse the CSV data, d3-scale for the ordinal color encoding, and d3-shape’s `d3.pie` and `d3.arc` to compute and render the arcs as SVG paths. Labels are positioned using the arc centroid method.

Pie chart

This interactive pie chart visualizes age-group distributions for six U.S. states, toggling between "apples" and "oranges" datasets via radio buttons. Built with D3.js v5, it uses `d3.pie` to compute arc angles, `d3.arc` for rendering donut segments, and `transition.attrTween` with an arc interpolation function to animate updates smoothly. A legend of colored dots and labels appears alongside the chart, with each state’s age categories mapped to a categorical color scale. The data loads from a local JSON file, and the SVG renders with styled strokes and transitions.

Fork of Pie chart RDW

This pie chart displays the distribution of four age groups—0-20, 20-40, 40-60, and 60+—with equal counts of 6, 6, 9, and 9 respectively. Using D3.js v6, the visualization builds an SVG with `d3.pie()` to compute arc angles and `d3.arc()` to generate the path shapes and label positions. A categorical color scale (`d3.scaleOrdinal` with `d3.schemeCategory10`) fills each slice, and text labels are placed via `label.centroid()`. The chart is centered through an SVG transform and styled with CSS.

Pie chart

This visualization presents the distribution of survey respondents across different age groups using a pie chart. The chart is rendered as an SVG using React and D3 v5, with each section colored distinctly and labeled with a data value. Data is loaded asynchronously from a CSV file using `d3.csv`. The code constructs the pie using `d3.pie`, generates arcs with `d3.arc`, and applies colors via `d3.scaleOrdinal`. A legend, created with SVG `<rect>` and `<text>` elements, maps each color to its age group and member count.

Pie chart with annimation

This interactive pie chart displays six categorical values under three selectable datasets (“Total,” “Option 1,” “Option 2”) with a donut layout and legends. It animates slice arc changes using D3’s `transition` and `attrTween`, interpolating between old and new arc paths when switching datasets via radio buttons. The SVG rendering includes slice paths, label polylines, and tooltips on mouseover, while colors come from `d3.scale.category20()`. The code mixes d3.v4 and d3.v3 APIs, including `d3.layout.pie` and `d3.svg.arc`.

Animated Fractal Pie Chart

This animated fractal pie chart displays a nested hierarchy of slices, where each slice recursively contains its own children, creating a visually intricate pattern with overlapping, scaled-down pie segments. The animation reveals the recursive structure by smoothly rotating and scaling each nested group. Built with D3 v4 and the d3-component library, the visualization renders with SVG elements whose transforms are animated over time. It recursively generates data using a set of fixed ratios and uses `d3.pie` and `d3.arc` for slice geometry, with a custom `d3.timer` to drive the animated transform sequence.

Untitled

This example shows a donut-style pie chart of population by age groups, with colored arcs labeled directly on the chart and a legend listing each age range alongside its population count. The chart uses d3.csv to load age-pop.csv from a remote URL, d3.layout.pie to compute arc angles from the population field, and d3.svg.arc to render the segments. Colors come from d3.scale.category20(), while the legend and arc labels are added as SVG text and rect elements appended to the same svg container.

Pie charts labels

This variation of a donut chart demonstrates how to label each slice with text and leader lines that extend outward. A button click triggers a transition to new random data, with all elements—arcs, labels, and polylines—smoothly animating to their new positions. The visualization uses D3.js v3, employing `d3.layout.pie` for the pie layout, `d3.svg.arc` for the donut and outer arcs, and `transition.attrTween` with `d3.interpolate` to morph values. Text labels are positioned via `outerArc.centroid` and aligned left or right based on the slice’s mid-angle.
