A radar chart displays multiple series of data as colored polygons overlaid on a circular grid of axes, with each axis representing a category. Values are scaled relative to the dataset’s maximum, and percentage labels mark the grid levels. The code uses D3 v3 to build the SVG, calculating polygon points from trigonometric functions and animating fill opacity on mouseover. Grid lines, axis labels, and legends are drawn with `d3.select` and `append`, while color is assigned via `d3.scale.category10()`.

Radar chart

A radar chart compares multiple quantitative variables on axes radiating from a common center. The code uses D3 v3 with SVG rendering and animation to plot one or more data series as filled polygons, with hover states that adjust fill opacity. Axis labels and percentage level markers are drawn using D3’s selection and append methods, while `d3.scale.category10` handles color encoding. The dataset is supplied inline, and the chart is rebuilt dynamically through a custom `RadarChart.draw` function.

Radar chart

A radar chart displays multivariate data as a polygonal series overlaid on concentric circular gridlines and radiating axes. Multiple data series appear as distinct filled polygons, with hover interactions that dim other areas to highlight the selected series. The visualization is built with D3 v3, rendering SVG elements like lines, polygons, and text. Axis labels and grid values are positioned using trigonometric calculations, while the data is sourced from the gist’s embedded dataset and animated transitions respond to mouse events.

Radar chart

This example shows a radar chart with multiple overlaid polygon series, each representing a set of values across several axes. Circular grid lines and labeled axes display the scale, with value markers at each level. The code uses D3 v3 to build the visualization in SVG, computing polygon coordinates from the data and drawing them with `d3.select` and appended elements. Hovering transitions fill opacity, and the `d3.format` API formats the axis labels.

Radar Chart D3 V4

This radar chart displays multiple data series as overlapping polygons across five concentric levels, with each axis labeled for a district such as Central or Kensington. Built with D3 v4, it uses SVG elements and custom drawing functions to construct the circular grid, axes, and value areas. The chart supports mouseover transitions that emphasize individual polygons, and it loads JSON data to render values scaled to a maximum of 100.

Radar Chart D3 V4

This example demonstrates a radar chart built with D3 v4, redesigned to improve the visual appeal of the original implementation by alangrafu. It renders an SVG-based spider chart with six axes, each labeled with a neighborhood name, and uses semi-transparent filled polygons to represent data series. The chart includes circular level lines and percentage labels, with axes extending from the center. The code defines a reusable `RadarChart.draw` function that accepts data and customizable options, and the example uses two series (e.g., Central and Picton) with hover interactions. The visualization is animated and styled with the Fira Sans font. The data shown is a single series with six areas, though the code supports multiple series.

Radar chart

This radar chart visualizes cluster data from a CSV file, comparing multiple financial metrics across five clusters. Each cluster is represented as a filled polygon overlaid on a web of axes, with angular rings showing value levels. The chart uses D3.js v3 with SVG rendering and hover interactions that highlight a selected cluster by reducing the opacity of others. Axes and labels are drawn from the dataset columns, and the polygons are built using D3’s data join and `transition` for smooth opacity changes.

Smoothed Radar Chart

This example presents a smoothed radar chart, also known as a spider graph, for comparing the budget allocation and actual spending of an organization across six categories like Sales and Marketing. Three distinct data series are overlaid as colored, semi-transparent polygons, with an interactive legend and axis labels. The visualization is built using the D3.js library (v5) and renders as an SVG with a custom `RadarChart` function that handles circular grids and curved paths. It also supports animation, a configurable maximum value, and a unit suffix for the data format.

Smoothed Radar Chart

This example presents a smoothed radar chart (also known as a spider graph) that compares multiple quantitative axes—such as Sales, Marketing, and Development—across three distinct categories, each assigned a unique color and legend. The visualization uses D3 v4 to render SVG paths with rounded strokes and animated transitions, while offering configurable options for levels, maximum values, units, and custom color scales. The chart draws circular grid lines and axis labels, with data from an inline dataset representing budget allocations and actual spending.
