This pie chart displays total sales aggregated by state, sourced from a CSV file loaded via `d3.csv`. It uses `d3.rollup` and `d3.sum` to group the data, then renders slices with `d3.pie` and `d3.arc` in an SVG. Each slice is colored with `d3.scaleOrdinal` using `d3.schemeTableau10`, labeled with state names, and accompanied by a legend showing totals. The visualization is built entirely with D3 v7.

Fork of Pie Chart

This example visualizes state sales data as a pie chart, with each slice colored by total sales value and a corresponding legend listing state names alongside their formatted dollar amounts. The top ten states by sales are shown, sorted in descending order. Built with React and D3 v5, it uses d3.pie, d3.arc, and d3.scaleOrdinal to generate SVG paths, while d3.csv loads the external dataset from a GitHub gist. Mouseover events log slice data to the console, and all rendering occurs within an SVG container.

Pie chart

A pie chart displays the top 10 states by YTD sales, with each slice colored and paired with a legend showing the brand name and value. The chart uses `d3.pie` to compute angles and `d3.arc` to render SVG paths, with `d3.scaleOrdinal` assigning colors. Data loads from a CSV via the `csv` method, and the legend includes formatted values using `d3.format`. The SVG is sized 960×500, with the pie centered and legend positioned to the right.

Pie Chart

This example presents a pie chart depicting the total sales distribution across item categories, sourced from a CSV file. The visualization includes a legend, a title, and a subtitle, with each slice labeled by its category and dollar amount. Built with D3.js v6, the code uses `d3.pie()` and `d3.arc()` to generate the chart, `d3.rollups` to aggregate the data, and `d3.scaleOrdinal` with `d3.schemeCategory10` for coloring. The chart is rendered as SVG elements, with annotations and labels positioned using arc centroids.

Fork of Pie Chart

This example displays the total sales figures for the top 10 US states as a pie chart, with each segment sized proportionally to its sales value. The visualization includes a legend showing state names and formatted dollar amounts, and hovering over a segment logs that state’s sales to the console. Built with D3 v5 and React, it uses `d3.csv` to load data from a GitHub gist, `d3.pie` to compute angles, `d3.arc` to generate SVG paths, and `d3.scaleOrdinal` with `schemeCategory10` for colors. The data is sorted descending before rendering.

pie_sales

This pie chart visualizes product sales from a CSV file, displaying each product’s share as a colored slice with labels positioned at each slice’s centroid. The chart uses d3.pie() to compute arc angles and d3.arc() to render the SVG paths, with a d3.scaleOrdinal and d3.schemeCategory10 providing color encoding. A legend below the chart lists each product and its corresponding sales value, generated from the same loaded data. The visualization is built with D3 v7 and rendered as inline SVG within an HTML container.

Pie Chart

This pie chart displays the sales figures of various companies, with each slice sized proportionally and labeled with its value in thousands. It also includes a color-coded legend listing company names and corresponding sales amounts. The visualization uses D3 v5 APIs including `pie`, `arc`, `scaleOrdinal`, and `format` to generate the SVG segments and text, with data loaded via `csv` from a GitHub gist. Colors are assigned through a custom ordinal scale.

Fork of Pie Chart

This visualization shows car sales for the month of May, displaying each state's count as a slice of a pie chart with proportional labels and a corresponding legend. The chart uses d3.pie and d3.arc to generate the segments, d3.scaleOrdinal for colors, and d3.select to manipulate the SVG. Data is loaded asynchronously from a GitHub-hosted CSV using d3.csv. Labels apply a custom d3.format tick format, while the legend lists state names and their values.

Pie chart-Mahesh-ICE 7

This pie chart visualizes Amazon’s 2022 revenue by state, showing each state’s proportional share of total revenue. The chart uses D3 v5’s `pie()` and `arc()` generators to compute and render SVG slices, with a legend on the right listing states and their revenue values. The code fetches data from a CSV file via `csv()` and colors each slice using `scaleOrdinal`. Text labels display revenue in thousands (e.g., “12.34K”), formatted with D3’s `format()`. The visualization is rendered entirely with SVG, and the legend includes both state names and corresponding revenue amounts.
