This example presents a nested donut chart that visualizes product purchasing behavior across Finnish households. The chart breaks down the total population into segments showing general purchase habits, then focuses on a specific product’s market share and the simulated effect of a 5% price increase. The visualization is built with D3.js (v3.5.5) using the `d3.layout.pie` and `d3.svg.arc` APIs to render concentric rings with distinct color scales. The SVG rendering includes interactive mouseover highlighting, and the data is structured as static JavaScript arrays showing household amounts and percentages.

pie chart

A pie chart visualizes the proportion of sales across three product categories—Electronics, Clothing, and Food—using hardcoded data from an array. The chart is rendered as SVG with D3.js v7, employing `d3.pie()` to compute arc angles and `d3.arc()` to generate the path shapes, which are filled using a categorical color scale. Each slice includes a centered text label displaying the category and sales value, while a separate legend lists the categories with their corresponding colors.

Pie chart

This pie chart example shows a donut-shaped chart with a solid orange center, rendered as an SVG using D3 v5. The chart displays four data segments (10, 20, 30, 60) with a color scale based on `d3.scaleOrdinal`, while radio buttons allow switching between apple and orange datasets (though only the orange dataset is actively rendered). The visualization uses `d3.arc()` to generate both the outer ring and inner circle paths, with the chart positioned at three-fifths of the SVG height.

Making an Interactive Pie Chart

This interactive donut chart displays income distribution across Sales, Dividends, and Interest using a D3 pie layout and arc generator. Hovering over a slice reveals a tooltip showing the percentage of the total amount, calculated with d3.sum. The chart uses a color scale with ordinal colors, labels positioned via arc centroids, and SVG rendering. Data is loaded from a CSV file, and the tooltip fades in and out based on mouseover and mouseout events.

Pie Chart

This interactive pie chart visualizes product sales distribution across years, with a dropdown selector allowing users to switch between 2018 and 2024 data. The chart displays percentage labels on slices larger than 5% and includes a color-coded legend for product identification. Built with D3 v7, the example uses d3.csv to load product sales data, d3.pie for arc generation, d3.arc for slice paths, and d3.scaleOrdinal with d3.schemeCategory10 for colors. All elements render as SVG within a styled HTML container.

pie chart

A pie chart visualizes customer spending across four categories—Food, Clothing, Electronics, and Entertainment—using quantitative values. Built with D3.js v7, it renders an SVG slice for each category, sized by its value, with labels positioned at each slice’s centroid. A color scale from `d3.schemeCategory10` and `d3.scaleOrdinal` map categories to fills, while `d3.arc` and `d3.pie` compute the geometry. A separate HTML legend lists each category with its corresponding color and value. The chart uses a fixed 500×500 pixel canvas and is re-rendered by clearing and redrawing the SVG elements.

D3 Layouts - Pie charts

This example shows a donut-shaped pie chart that visualizes a small dataset of six numeric values. The chart is rendered as an SVG, with each value displayed as a white label at the centroid of its corresponding arc. The code uses D3’s `pie` layout generator to compute the arc segments, `d3.arc` to define the ring’s inner and outer radii, and `d3.scaleOrdinal` with `d3.schemeCategory10` to assign categorical colors. The chart is drawn using D3’s select/append API on a blank HTML page.

Piechart

A pie chart displays chocolate sales proportions by product category. The visualization uses D3.js version 7, loading data from a CSV file and mapping category values to colors with `d3.scaleOrdinal` and `d3.schemeSet2`. The `d3.pie()` and `d3.arc()` functions generate the chart geometry, rendering each segment as a filled SVG path with white strokes. A custom HTML legend, built with D3 selections, labels each category using the same color scale, while the page layout is styled through external CSS.

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.
