Four small donut charts display proportional breakdowns for each row of a two-dimensional numeric array. D3 v3’s `d3.layout.pie` computes arc angles, while `d3.svg.arc` renders the path shapes. Each chart uses an inner and outer radius, with colors assigned by index from `d3.scale.category20c()`. The SVG elements are generated per row, and the totals for each row differ.

AI-generated description

An example of multiple pie (donut) charts created with D3. The data is represented as a two-dimensional array of numbers; each row in the array is mapped to a pie chart. Thus, each pie represents the relative value of a number (such as 1,013) within its rows. Note that in this dataset, the totals for each row are not equal.

D3: Pie layout

This example shows a donut chart built with D3.js, displaying six numeric values as colored arc segments arranged around a central hole. Each segment is labeled with its corresponding value, positioned at the centroid of the arc. The visualization uses the `d3.pie()` layout to compute the angles and `d3.arc()` to generate the SVG path shapes, with an ordinal color scale (`d3.scaleOrdinal` and `d3.schemeCategory10`) assigning colors. Data is hardcoded as an array, and all rendering is done via SVG elements in d3.v4.

pie

A pie chart displays eight proportional segments with values from the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, 21). D3 v4’s `d3.pie()` computes the arc angles, while `d3.arc()` generates the SVG path for each slice with an inner radius of 0 and outer radius of 100. A `d3.scaleOrdinal` with `d3.schemeCategory10` assigns categorical colors, and white strokes separate the segments. The chart is rendered as static SVG elements, translated to position (200, 200) within the viewport.

D3 Layouts - Pie charts

This example shows a donut-shaped pie chart that visualizes a small dataset of six numeric values. The chart is rendered as an SVG, with each value displayed as a white label at the centroid of its corresponding arc. The code uses D3’s `pie` layout generator to compute the arc segments, `d3.arc` to define the ring’s inner and outer radii, and `d3.scaleOrdinal` with `d3.schemeCategory10` to assign categorical colors. The chart is drawn using D3’s select/append API on a blank HTML page.

Pie Multiples with Nesting

Four small donut charts display the distribution of airline carriers at four US airports. Each chart represents a single airport, with arcs sized by passenger count and colored by carrier. The visualization loads CSV data from `flights.csv` and groups entries by airport using `d3.nest`. The `d3.layout.pie` computes arc angles, while `d3.svg.arc` generates the SVG paths, with a rotated label added for larger segments.

Pie chart

A pie chart displays the proportional breakdown of a categorical variable, using colored slices to represent each category's share of the whole. The example renders a fixed dummy dataset (`{a: 9, b: 20, c:30, d:8, e:12}`) as SVG paths, with each slice's angle determined by `d3.pie` and its geometry drawn via `d3.arc`. Colors come from `d3.scaleOrdinal` with a manually specified palette, and the chart is centered within a 450×450 pixel canvas. The code uses the D3.js v4 library, appending the visualization to a `<div>` and styling slices with black strokes and 0.7 opacity.

Pie chart TT

This example presents a simple pie chart built with D3.js (v4), visualizing a small static dataset of four numeric values. The chart is rendered as SVG within an 800x700 viewport. The code uses the `d3.pie()` layout generator to compute arc segments and the `d3.arc()` function to draw the resulting paths. Each slice is filled with a distinct color from a predefined array. The implementation also highlights direct manipulation of the `d3.arc()` API by logging arcs generated with both computed and constant angle/radius parameters, demonstrating how the path data is constructed.

Pie chart

A pie chart displays the proportional breakdown of four hardcoded values, with a color legend assigned via a radio button group offering apples or oranges datasets. The visualization renders as an SVG donut using D3 v5's `d3.pie()` and `d3.arc()` generators, with an ordinal color scale mapping categories to distinct hues. The chart draws all arcs at once from a fixed data array, and changing the dataset radio button does not trigger a re-render, as only the initial render function is called.

Pie chart

This pie chart example shows a donut-shaped chart with a solid orange center, rendered as an SVG using D3 v5. The chart displays four data segments (10, 20, 30, 60) with a color scale based on `d3.scaleOrdinal`, while radio buttons allow switching between apple and orange datasets (though only the orange dataset is actively rendered). The visualization uses `d3.arc()` to generate both the outer ring and inner circle paths, with the chart positioned at three-fifths of the SVG height.
