This example visualizes the distribution of survey respondents across different age groups as an interactive pie chart, with each slice labeled with its corresponding value and accompanied by a color-coded legend. The chart uses D3.js v5 within a React framework, employing the `pie()` and `arc()` functions to compute the arc paths and the `scaleOrdinal()` for color mapping. Data is fetched asynchronously from a CSV file using `d3.csv`, and the SVG rendering includes custom text placement via `arcGenerator.centroid()` for labels.

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.

Fork of Fork of Pie chart

This example displays an interactive pie chart showing the distribution of survey participants across different age groups, with each slice labeled with its value and accompanied by a legend listing age groups and member counts. The visualization fetches CSV data from a remote GitHub gist using `d3.csv`, then renders SVG paths with `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` for color mapping. Text labels are positioned using `arc.centroid`, and the legend is built manually with SVG rectangles and text elements. The chart is styled with custom CSS, including hover-free static rendering and a centered title.

Fork of Pie chart

A donut chart displays the distribution of survey respondents across different age groups, with each segment colored distinctly and labeled with its corresponding value. Legends on the right identify each age group and its member count. The visualization uses D3 v5’s `pie` and `arc` generators to compute segment paths, `scaleOrdinal` for color mapping, and `format` for number formatting. Data is fetched as CSV from a GitHub gist, and the SVG is rendered within a React component.

Activity_7.1

This example shows a pie chart of survey responses by age group. The chart is built with d3.pie() and drawn with d3.arc(), colored using d3.scaleOrdinal() with the d3.schemeCategory10 palette. Each slice is labeled with its age group, and a legend on the upper left matches colors to categories. Data is loaded asynchronously from a remote JSON file using d3.json(). The visualization is rendered as SVG within a fixed 500 by 400 pixel viewport, with all graphical elements customized through D3’s selection and attribute methods.

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 with React

This example demonstrates how to build an interactive pie chart using React and D3.js. It visualizes categorical data from a CSV file, showing the distribution of letters A through G with corresponding count values. The chart displays colored pie segments with letter labels, alongside a legend that shows each letter and its count. Users can click on either pie segments or legend items to highlight a specific category, dimming the others. The implementation uses D3's `pie` and `arc` generators for creating the pie geometry, `scaleOrdinal` for color mapping, and React's `useRef` and `useState` hooks for managing state and rendering with the `ResizeObserver` to handle responsive dimensions.

ICE-7: Pie Chart with labels

This example shows the population distribution across age groups as a pie chart. The visualization displays a colored slice for each age group, with labels placed inside the slices and a legend on the right detailing each group's name and population. The chart is rendered as an SVG using D3.js v3, loading data from a CSV file via `d3.csv`. The code defines arc geometry with `d3.svg.arc` and `d3.layout.pie`, applies a categorical color scale via `d3.scale.category20`, and positions labels using the centroid calculation `arc.centroid(d)`.

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.
