This interactive donut chart displays the proportional sizes of five oblasts, with a legend showing each region’s percentage value. A menu allows the user to switch between plotting population, total, COVID, or other data categories, which updates the arc sizes and legend percentages accordingly. The visualization is built with React, rendering SVG paths generated by d3.pie and d3.arc, while d3.scaleOrdinal maps region names to colors. An unused helper embeds d3.interpolateRgb for a color gradient, and the menu responds to click events.

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.

Fork of Pie Chart

A forked pie chart visualizes the distribution of new COVID-19 tests across geographic locations, using a D3 v5 pie layout with an SVG rendering. The chart shows the top 10 locations by test count, with each slice’s fill color and legend labels derived from the `d3.scaleOrdinal` and `d3.schemeCategory10` palette. Data is loaded from a CSV via `d3.csv`, sorted descending, and rendered with `d3.pie` and `d3.arc`; hover events log values to the console, and legends display each location’s name and test total. The React-based example is presented in an HTML page with custom CSS styling.

Fork of Pie Chart

A pie chart displays population values for the top 10 most populous years from a CSV dataset, with each slice colored by category and an interactive tooltip logging data on mouseover. The visualization uses D3 v5's `pie` and `arc` generators to compute and render SVG paths, while `scaleOrdinal` with `schemeCategory10` assigns colors. A legend lists years with corresponding population figures, and the data is sorted descending before rendering. The chart is built within a React-compatible setup using D3's `select` and `csv` loading.

Pie chart for report

This example presents a pie chart that visualizes population data for three continents (Africa, Europe, and Australia), with each slice labeled by continent name. The chart is built using React components and D3.js v6, specifically leveraging `d3.pie()` to compute slice angles, `d3.arc()` to generate SVG paths, and `d3.interpolateRgb()` to apply a color gradient from deep red to light orange. The SVG rendering includes slices with calculated centroids using `arc.centroid()` for text positioning, while the unused `Check` component demonstrates a separate color-scale experiment.

Pie chart in React & D3 - with Legend

A React and D3 donut chart visualizes budget allocations across five categories, with a legend mapping category names to a color scale interpolated between coral and crimson. The `pie` and `arc` generators compute slice geometry, while `scaleOrdinal` assigns colors from the interpolated range. Percentages appear on slices via `arc.centroid`, and the `ColorLegend` component renders interactive-free color swatches with tick spacing. The chart uses SVG rendering with `d3.interpolateRgb` for gradient transitions and `format` for numeric labels, based on static data in the `donThemes` array.

Pie chart

The visualization displays two interactive pie charts comparing apple and orange counts across five regions, with a toggleable radio interface to switch datasets. Built with D3.js (v5.16.0), it renders an animated SVG donut chart using `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` color scales. Legends appear as colored dots and labels beside the chart. On dataset change, arcs transition smoothly via `transition.attrTween` with interpolation, and a delayed auto-animation replays the arc tweens every two seconds. Data is loaded asynchronously from `data.json` via `d3.json`.

Fork of Pie chart in React & D3 - 1st attempt

A React and D3 pie chart renders four slices with a color scale interpolated from #eaaf79 to #bc3358 using d3.interpolateRgb. The chart uses d3.pie() and d3.arc() to compute and draw each SVG path, with inner and outer radii defining a donut shape. A secondary component defines a checkered color ramp from #0F8C79 to #f2f2f2, though it is commented out. Unused legend data for five named categories is declared but not rendered.

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.
