This bubble chart displays the cardinality of six clusters from a JSON dataset, with each cluster represented as a colored circle scaled by its size value. Built with D3.v4, the visualization uses the `d3.pack` and `d3.hierarchy` APIs to compute circle positions and radii, rendering nodes as SVG groups with attached circle and text elements. The input data is loaded asynchronously via `d3.json`, and the chart is generated within an 500-pixel square SVG canvas.

Bubble Chart - Clustered

Four clusters of proportional circles, each labeled with a group letter (A–D), fill the entire SVG canvas without overlapping. The bubble sizes correspond to each group’s `percentResponse` value, while the cluster layout is computed using `d3.pack()` on a `d3.hierarchy()` root. Rendered with `d3.v7` in a React framework, the circles and labels are appended as SVG elements with `d3.select` and `join()`. The data source is hardcoded dummy data, with no axes or tooltips.

Bubble Chart

A bubble chart encodes hierarchical data as a packed circle layout, with each circle’s area proportional to a numeric value and color representing its top-level package. The visualization uses D3 v4’s `d3.pack` and `d3.hierarchy` to compute the layout, then renders SVG circles and clipped text labels. Data comes from the Flare class hierarchy stored in a CSV file. Hovering reveals the full class name and formatted value via SVG `<title>` elements.

Category clustered Bubble Chart

This example shows a clustered bubble chart where circles are grouped by color-coded regions, with bubble size representing total cost and labels indicating country. The visualization uses D3.js v7 with a d3.pack layout to position circles within a hierarchical cluster structure, processing data from a CSV file loaded via d3.csv. SVG renders the circles and text labels, while a custom HTML tooltip displays country, region, and cost details on mouseover, with d3.scaleOrdinal mapping region values to a color palette.

Circle-Packing II

This visualization displays a hierarchical bubble chart of the Flare dataset, where each circle’s area encodes a numeric value and its color reflects the data’s grouping structure. Built with D3 v4, the chart uses `d3.pack` to compute non-overlapping circle positions within a fixed canvas, with each node labeled by its class name and tooltip showing the raw value. The SVG rendering applies a clip-path to each node so text remains contained within its circle, and hovering highlights the selected bubble.

Loading json files

This example demonstrates an interactive circular bubble chart that visualizes hierarchical JSON data, with a focus on handling multiple datasets. The visualization uses D3 v3’s `d3.layout.pack` to position and size circles based on nested data values, while a click-to-zoom animation transitions between hierarchy levels. Users can switch between three JSON files via buttons, which are implemented as SVG groups with click handlers that reload and re-render the pack layout. The code uses `d3.json` for asynchronous data loading, `d3.scale.linear` with HCL color interpolation for node coloring, and `d3.interpolateZoom` for smooth zoom transitions.

bubble one more time

A force-directed bubble chart displays individual BMI measurements grouped by race and sex, with circle radius proportional to BMI value and color encoding racial categories. Using D3 v3 and SVG rendering, the visualization loads data from a CSV file and applies a cluster force layout with collision detection to arrange bubbles into distinct groups. The code implements custom `cluster` and `collide` functions alongside the `d3.layout.force` simulation, while a tooltip on mouseover reveals each bubble's race, BMI, and sex. Circles are colored via an ordinal scale and positioned through the force layout's tick handler.

Exploración1

This example visualizes a dataset of yearly counts as a circular bubble chart, where each circle’s size encodes a numeric value and its color represents a category derived from the data’s ID. The visualization uses D3.js v5 to load a CSV file with `d3.csv`, then applies the `d3.pack` layout to compute circle positions and radii, with `d3.hierarchy` structuring the data. Each leaf node is drawn as an SVG `<circle>` with a fill color from `d3.scaleOrdinal(d3.schemeCategory20c)`, and text labels are added with clipping paths to keep them inside the circles. The chart also includes tooltips via `<title>` elements showing the exact value for each circle.

D3 v5 Circle-Packing

This visualization shows a hierarchical dataset as nested circles, with each circle’s size encoding a numeric value and its color representing depth in the tree. Built with D3 v5 and rendered as SVG, it uses `d3.stratify` to convert the tabular flare.csv data into a hierarchy, `d3.pack` for layout, and `d3.scaleSequential` with `d3.interpolateMagma` for coloring. Hovering highlights a node and its ancestors via the `mouseover` and `mouseout` events.
