This example displays multiple pie charts overlaid on a geographic map of the world, using D3 v4 with SVG rendering. A Mercator projection centered on India provides the base map, drawn from TopoJSON land and country boundary data. Each pie chart is positioned at coordinates read from a CSV file and represents a static distribution via five categorical slices, colored with the Category10 scheme. The visualization also includes small red circles at each data point, and the chart arcs are generated with d3.arc and d3.pie, demonstrating how to layer pie charts on map points.

Based on a question at stack overflow, regarding multiple pie charts on a map.

d3v3 Multiple Pie Charts on Map - Static Data

This example overlays multiple small pie charts on a world map, with each pie positioned at a geographic coordinate from a CSV file. The map uses a Mercator projection centered on India, with countries rendered as green landmasses and white borders via TopoJSON. Each data point is plotted as a small pie chart using d3.layout.pie and d3.svg.arc, with slices colored by category10 scale; a red dot marks each location. The visualization combines geographic context with proportional composition, illustrating how static CSV data can be overlaid onto a map using D3 v3 and SVG.

d3v4 Multiple Pie Charts on Map - Data from CSV

This example shows multiple pie charts overlaid on a geographic map, with data loaded from a CSV file. The map is rendered in SVG using d3.geoMercator projection and topojson, with country land areas and mesh borders drawn in green and white. Pie charts are positioned at latitude-longitude coordinates from the CSV using the same projection, with each pie's slice values parsed from a hyphen-separated string. Labels appear above each chart, and pie slices use the categorical color scheme. The visualization combines geographic context with proportional data display, allowing viewers to compare categorical breakdowns across multiple map locations.

d3v3 Multiple Pie Charts on Map - Data from CSV

This example shows a map of India with seven small pie charts positioned at the locations of water-quality monitoring points. Each pie chart encodes the distribution of data values from a CSV file, with each slice colored by category. The map is rendered using a Mercator projection of a TopoJSON world dataset, with landmasses filled green and country borders drawn as white mesh lines. Pie charts are placed using the geographic coordinates (longitude/latitude) from the CSV, with a label above each chart. The pie layout and arc generator from d3.v3 are used to create the charts, with values parsed from a dash-separated string in the data column. Colors are assigned via a categorical scale, and the visualization combines geographic and statistical data in an SVG canvas. The example is based on a Stack Overflow question about plotting pie charts over map points with D3.js.

pie chart

This pie chart visualizes country populations using D3.js v6, rendering each slice as an SVG path with a categorical color scale. The code loads CSV data from a GitHub gist, processes population values, and uses d3.pie() and d3.arc() to generate the chart geometry. Each slice is labeled with its country name positioned at the arc centroid, while a custom legend built from SVG rectangles and text elements displays the color assignments alongside the chart.

Orthographic Pie Chart

A pie chart rendered as geographic features is projected onto an orthographic globe using D3 v4. The example converts SVG arc paths into GeoJSON via a custom module that samples path coordinates and translates them into geographic coordinates. The globe and pie chart rotate together in an animation.

Fork of Let's make a map with D3.js!

This visualization combines a D3.js v4 Mercator projection map of world countries with layered pie charts representing water quality data from a CSV. The map renders landmasses in green with white mesh borders, while each data point uses a red circle and an overlaid pie chart built with `d3.pie` and `d3.arc`. Country boundaries are generated using the `topojson` library on a world-atlas GeoJSON source, and the pie charts’ angles reflect the comma-separated values in the `data` field. The color scheme for the slices comes from `d3.schemeCategory10`.

D3 Example

This example shows small multiples pie charts comparing the religious breakdown of the world’s five most populous countries, with each pie’s area scaled proportionally to that country’s total population. The visualization uses D3’s nested selections and d3.layout.pie with d3.svg.arc to draw the charts, d3.scale.sqrt for the population-based radius, and d3.legend.color for the categorical color key. Data comes from the Pew Research Center’s Global Religious Landscape dataset, loaded from a CSV file.

D3 + Leaflet: Pie

This example shows six pie charts overlaid on a Leaflet map, each encoded at a geographic coordinate and sized with a red-and-gray split representing an `achieve` value between 0 and 1. The code uses Leaflet’s `latLngToLayerPoint` to convert geographic positions into SVG screen coordinates, and d3.v3’s `d3.svg.arc` and `d3.layout.pie` to generate the pie paths. The SVG layer is attached to the map via `map._initPathRoot()`, and the chart positions update on the map’s `viewreset` event. The source data is a hardcoded array of lat/lng pairs with achievement ratios.
