This example shows a smoothed radar chart comparing multiple entities across four axes, with values for hospital metrics and product attributes. The visualization uses D3.js version 3.5.6 to render an SVG with seven concentric grid levels, radial axes, and glowing area blobs that represent each data series. The chart applies a cardinal-closed interpolation for smooth blob outlines, includes a color scale for series distinction, and adds a glow filter via SVG defs. The legend and tooltip appear in the interface, with animated rendering handled through React starter code.

Smoothed D3.js Radar Chart

This example shows a smoothed radar chart comparing multiple entities across several dimensions, with data for hospitals and products rendered as overlapping, semi-transparent polygons. The visualization uses D3.js version 3.5.6 to generate an SVG with circular grid lines, radiating axes, and animated blobs, with a glow filter added for visual emphasis. It relies on D3 scales for ordinal colors and linear radius mapping, with options for rounded strokes, tooltips, and level labels. The chart is built for React integration and uses static, embedded data arrays.

Smoothed D3.js Radar Chart

A smoothed D3.js radar chart compares multiple entities across four axes, using SVG rendering and animated transitions to display overlapping, semi-transparent polygons. The example plots hospital metrics—such as running cost, beds, nurses, and consultants—against five data series, each assigned a distinct color via an ordinal scale. Built with D3 v3 and React, the chart generates circular grid levels, axis lines, and radial labels, while a glow filter and round stroke option enhance the visual style. The radar chart function computes the maximum value from the dataset and scales radii accordingly.

Fork of Smoothed D3.js Radar Chart

This example shows a smoothed radar chart comparing multiple entities across four axes, including hospital metrics like running cost and bed count, rendered with D3.js v3. The chart uses an ordinal color scale and a logarithmic-like radius scale to draw circular grid levels, radial axes, and filled polygon blobs with stroke and glow filters. It includes an SVG-based interactive tooltip and legend, with all elements animated via D3’s data join and transition methods. The code relies on D3’s `d3.scale.linear`, `d3.scale.ordinal`, and `d3.range` to manage scaling and layout, and applies a cardinal-closed interpolation for smooth blob paths.

Smoothed D3.js Radar Chart

This gallery example presents a smoothed radar chart comparing smartphone attributes across three brands, using a dataset that scores features like battery life, brand, and price. The visualization displays aggregated values as colored, rounded polygons on a circular grid, with level labels and axes indicating value scales. The chart is built with D3.js version 3.5.6, using `<svg>` elements for rendering, a linear scale for radius, and an ordinal color scale to distinguish the three data series. The code includes a glow filter and calculates the maximum domain from the data to ensure all values fit within the plot.

Smoothed D3.js Radar Chart

This smoothed D3.js radar chart visualizes a single data series across six categorical axes (comp, con, und, red, acc, tim), with values displayed as a percentage-based polygon. The chart features five concentric grid levels, rounded strokes for the blob path, and colored dots at each data point, all rendered as SVG. Built with D3 v5, it uses a linear radial scale and a custom `RadarChart` function based on Nadieh Bremer’s design. The visualization includes responsive sizing and a static steelblue color scheme, with basic styling via CSS.

Smoothed D3.js Radar Chart

This example presents two smoothed radar charts created with D3.js, displaying skill assessments across five dimensions for each chart. The first chart uses a yellow palette to visualize "Visualization design" and related skills, while the second uses red for front-end and architecture skills. Data is normalized and rendered as circular, web-like axes with filled, rounded areas. The charts are generated using a custom RadarChart function that draws five grid levels, axis lines, and colored blobs, with options for level count, label sizing, and maximum value. The SVG rendering includes subtle drop shadows and a flex layout places the two charts side by side.

Fork of Smoothed D3.js Radar Chart

This example shows a radar chart comparing nutritional values across sixteen categories, including protein, fat, carbohydrates, calcium, and vitamins, for a single food item. The chart renders as a circular grid with five concentric levels, using SVG paths and smoothed, rounded strokes to create a distinct blob shape. It is built with D3.js version 3, leveraging the library’s linear scale for radial positioning, ordinal color scaling, and SVG filters for a glow effect. The visualization includes interactive hover tooltips and animated transitions, with data displayed as percentage values.

Smoothed D3.js Radar Chart

A smoothed D3.js radar chart displays a single data series with five axes—subject knowledge, sports, course design, personal qualities, and foundational courses—with values scaled from 0 to 5. It renders as an SVG with a circular grid of five levels, a glowing area path, and dots at each data point, using `d3.scaleOrdinal` for coloring and `d3.scaleLinear` for the radial scale. The chart applies rounded strokes for smooth path transitions and includes an animated glow filter via SVG `feGaussianBlur`.
