This example visualizes operating system market share using a pie chart with external labels and a legend. It displays Windows, macOS, Linux, and ChromeOS with their respective percentages computed from the raw CSV data. The visualization uses `d3.pie()` to compute slice angles, `d3.arc()` for rendering paths, and `d3.scaleOrdinal` with `schemeCategory10` for colors. SVGs are drawn via `d3.select`, and slices include white strokes, while labels are positioned using trigonometric calculations based on mid-angles.

Q1_VT

This example shows OS market share as a pie chart, with each segment labeled by its percentage value and accompanied by a legend listing operating systems and their shares in millions. Data is loaded asynchronously from a CSV file using `d3.csv`. The chart is rendered with SVG paths generated by the `d3.pie` and `d3.arc` generators, with categorical colors assigned via `d3.scaleOrdinal`. Segment labels are positioned using `arcGenerator.centroid`, and values are formatted with `d3.format`.

1 q -pie chart task 9

This pie chart visualizes the market share of operating systems as a proportion of a whole. The chart is rendered as an SVG using D3.js (v7), with each slice sized by the `Market_Share` value and labeled with the `Operating_System` name. The data is loaded from a remote CSV file via `fetch` and parsed with `d3.csvParse`. Slice colors are assigned using a categorical color scheme (`d3.scaleOrdinal` with `d3.schemeCategory10`), and the pie geometry is computed with `d3.pie` and `d3.arc`, with labels positioned via the `labelArc` centroid.

Visualization with D3.js

This pie chart visualizes operating system market share percentages for Android, Windows, Linux, and iOS. The visualization uses D3.js version 5 to bind the dataset to SVG elements, computing arc paths with `d3.pie()` and `d3.arc()`. A `d3.scaleOrdinal` with `schemeCategory10` assigns colors to each slice, and labels are positioned using `label.centroid()`. The example demonstrates basic pie chart construction with a small, hardcoded dataset in a single SVG container.

Learn D3.js

This example shows worldwide operating system market share for Android, Windows, and iOS as a labeled pie chart. It renders in SVG using D3 v4, with the `d3.pie` layout generating arc data from hardcoded percentages and `d3.arc` producing the path geometry. A `d3.scaleOrdinal` with `d3.schemeCategory10` assigns colors, while arc centroid labels display each platform and its percentage directly on the chart. The visualization demonstrates basic pie chart construction with group elements and path/text bindings.

Learn D3.js

This example shows worldwide operating system market share percentages in a static pie chart drawn with SVG. The code uses D3 v4’s `d3.pie()` to compute arc angles from three data objects and `d3.arc()` with `outerRadius` and `innerRadius` to generate the path shapes. A single `<text>` element per slice, positioned via `label.centroid(d)`, displays the platform name and percentage. Categorical colors come from `d3.scaleOrdinal(d3.schemeCategory10)`. The visualization is rendered inside an `svg.pie-chart` element in the HTML, with data hard-coded in the JavaScript array.

Assignment-2 Q1.1

This example visualizes browser market share data as a pie chart. The chart uses D3.js v7 to load CSV data from a GitHub gist and render it as SVG arcs, with each slice colored via `d3.scaleOrdinal` and `d3.schemeCategory10`. Interactive tooltips appear on mouseover, displaying the browser name and percentage. A legend lists each browser with a corresponding color swatch, and the chart includes a title and axis labels.

Pie chart

This pie chart displays browser market share percentages, with each slice colored via a categorical scale and a legend identifying the browser names. It uses D3 v7 with `d3.pie` and `d3.arc` to generate the SVG paths, and `d3.csv` to load the remote dataset. Hovering over a slice reveals a tooltip showing the browser and its exact share, while the chart includes a bold title and white stroke separators between slices.

Activity_7_11815718

This D3.js pie chart displays browser market share data for Q3 2025, loaded from a CSV file hosted on a GitHub Gist. Each slice is colored using `d3.scaleOrdinal` with `d3.schemeSet2`, and labeled with the percentage value. The chart uses `d3.pie` and `d3.arc` to generate the slices, with white stroke separating them. A legend on the right, built with SVG rectangles and text, identifies each browser. The visualization is rendered entirely as SVG within a 960x500 canvas.
