This pie chart example visualizes a sequence of eight numbers—1, 1, 2, 3, 5, 8, 13, 21—as proportional wedges. Using D3 v4, it renders the chart with the `d3.pie` layout function and `d3.arc` to draw each arc with fixed inner and outer radii. The SVG paths are filled using a categorical color scheme (`d3.schemeCategory20c`) via `d3.scaleOrdinal`. The graphic is centered inside a full-screen SVG, and the code demonstrates a basic, static pie chart built from a simple array.

Shapes: Pie Example

This example displays a small pie chart built from an array of seven numeric values, with each slice sized proportionally to its value. The visualization uses D3 v4’s `d3.scaleOrdinal` with the `d3.schemaCategory10` color palette to assign distinct colors to each segment. The chart is rendered as an SVG element, where the arcs are generated using the `d3.arc` API with an inner radius of zero and an outer radius of ten, and angles are computed via `d3.pie()` before being passed to the arc’s start and end angle functions. The data itself is hard-coded in the script, and the code originates from a gist by DanielAguirre, structured for use with Blockbuilder.

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.

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 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

A pie chart displays five categorical values as proportional, colored arcs with hover highlighting and percentage labels. The chart uses d3.layout.pie to compute arc angles and d3.svg.arc to generate SVG paths, with an ordinal color scale for fills. Hovering translates the arc group outward via a transition, while labels rotate to align with each segment’s midpoint. The visualization is built with d3.v3 and renders entirely in SVG.

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.

Easy Pie Chart

This example displays a simple pie chart with four slices, using colors and numeric labels to represent the provided dataset. The chart is built with D3 v4 on an SVG canvas, where a group element is centered and `d3.pie()` computes the start and end angles for each arc. These angles are rendered using `d3.arc()` with a specified inner and outer radius and pad angle, while `d3.scaleOrdinal` assigns the slice colors. Each wedge is labeled with its data value using `arc.centroid` to position the text.

D3 Piechart

This example shows a simple pie chart built from a static array of six numeric values, rendered as filled orange arcs with white strokes on an SVG canvas. The chart is generated using the d3 pie generator to compute arc segments, while the d3 arc generator defines the inner and outer radii for the donut-style shape. The visualization uses d3’s select and join methods to bind the computed arc data to SVG path elements, with styling applied through CSS and inline attributes.
