This pie chart visualizes monthly expense categories from a CSV file, displaying each category’s proportional share with a legend and value labels. Built with React and D3 v7, it uses `d3.pie` to compute arc segments and `d3.arc` to generate SVG paths, rendered with a categorical color scheme from `d3.scaleOrdinal`. The chart draws arcs and text labels onto an SVG canvas, with a legend constructed iteratively from the data.

Fork of React & D3 Starter

This pie chart visualizes monthly expenses across five categories: Rent, Food, Travel, Shopping, and Bills. The visualization uses D3 v7 to create an SVG-based donut chart with category labels positioned along the arcs and a legend displaying each category's name and corresponding value. It employs `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` with the `schemeCategory10` color palette to compute arc paths, position labels, and assign colors based on data loaded from a CSV file.

Fork of React & D3 Starter

This fork of the React & D3 Starter shows a pie chart of expense categories with quantitative values, alongside a reusable scatter plot module implemented as a factory function. The pie chart uses d3.pie and d3.arc to generate SVG slices, a d3.scaleOrdinal color scale, and includes text labels placed via arc.centroid plus an HTML legend. The scatter plot module uses d3.scaleLinear, extent, axisBottom, and axisLeft to render axes and circles, with setters for width, height, data, and value accessors. Data is hardcoded in both components, and rendering uses SVG throughout.

Fork of Pie Chart

This fork of a pie chart visualizes travel expenses by category, displaying each expense segment with its corresponding price label and an aligned legend that pairs color swatches with specification names and values. The chart uses D3 v5 APIs including `d3.pie()`, `d3.arc()`, and `d3.scaleOrdinal()` to compute the pie geometry and color mapping, with data loaded asynchronously from a remote CSV via `d3.csv()`. Rendered as an SVG, the chart positions segments and legend elements through D3’s selection and attribute methods, with text formatting applied via `d3.format()`.

Fork of Fork of loading data w/ react and d3

A pie chart displays the proportional distribution of named colors, using their RGB hex values for the fill color of each slice. The chart is built with React, which manages the asynchronous loading of a CSV file via `d3.csv` and conditional rendering, while ReactDOM mounts the component. The geometric layout and slice drawing rely on the D3 modules `d3.arc` and `d3.pie`, which compute the arc paths for each data row. The example demonstrates a minimal integration of D3’s data-processing and shape-generation functions within a React component structure, rendered as an SVG graphic.

Fork of HTML Starter

This pie chart visualizes expense categories and their corresponding values from a CSV dataset. Using D3.js v7, the chart generates colored slices with SVG paths via `d3.pie()` and `d3.arc()`, with white labels positioned at arc centroids. A legend constructed with SVG rectangles and text displays each category alongside a color scale based on `d3.scaleOrdinal` and `d3.schemeCategory10`. The data is loaded asynchronously with `d3.csv`.

Fork of Fork of Reusable D3 pie Plot

This household expenses pie chart visualizes the proportional spending across eight categories, such as Housing, Food, and Education, with each slice labeled by its percentage of the total. The chart is rendered using the D3 v7 library, which uses `d3.pie()` to compute arc data, `d3.arc()` to generate the SVG paths, and `d3.scaleOrdinal()` with `schemeCategory10` for colors. A legend on the right side lists each category with its original value, and the entire visualization is created with SVG elements. Data is loaded from a local `expenses.csv` file using `d3.csv()`.

Fork of Pie Chart React & d3

This interactive pie chart visualizes a categorical color palette dataset loaded from a CSV file via `d3.csv`. The React component manages the data with `useState` and `useEffect`, rendering an SVG where each slice corresponds to a row, filled with its `RGB hex value`. The chart uses `d3.pie` and `d3.arc` to compute and draw the pie geometry, with a large outer radius creating a striking radial composition. Data loads asynchronously, displaying a "Loading..." message until ready.

Fork of Fork of Rendering Data with React and D3

This example renders a dataset of CSS named colors as a pie chart, with each slice colored by its corresponding RGB hex value. The visualization loads the data from a CSV file using `d3.csv` and manages the asynchronous state with React’s `useState` and `useEffect` hooks. React renders the SVG paths, while D3’s `pie` and `arc` generators compute the slice angles and path geometry. The chart is centered using an SVG `<g>` transform, and the code includes commented alternatives for manual arc computation.
