This zoomable treemap template visualizes hierarchical agricultural data, organizing crops by category such as Plants, Vegetable, and Forage, with leaf size reflecting the numeric value for each plant. Users can click any cell to drill down into a sub-hierarchy, with animated transitions and a breadcrumb-style grandparent bar enabling navigation back up. Built with D3 v3, it uses the `d3.layout.treemap` for layout, `d3.scale.category20c` for color, and linear scales for positioning, rendering with SVG and CSS transitions. The data comes from a JSON file containing crop names, scientific names, and measured attributes.

Treemap2

A hierarchical treemap displays plant nutrient data, using colored rectangles to represent crop categories and individual species. Clicking a cell zooms into that branch, while the orange top label navigates back. The visualization uses the d3.v3 treemap layout with a custom recursive layout and accumulation function for zooming. Data is loaded from a CSV file via d3.csv, and transitions animate the zooming interaction.

Zoomable treemap template

Built with D3.js v3 and jQuery, this interactive visualization presents education resource data as a zoomable treemap. The code uses `d3.layout.treemap` to hierarchically arrange rectangles by value, colored via `d3.scale.category20c`, with click-to-transition zooming between parent and child nodes. Data is loaded from a JSON array of entries containing subject, region, subregion, and count values, which the treemap aggregates and lays out recursively. The SVG renders responsive rectangles and a grandparent breadcrumb header, demonstrating a reusable template for hierarchical exploration.

Zoomable treemap template

This zoomable treemap displays hierarchical data through nested rectangles sized by value, allowing drill-down navigation to explore subregions. It visualizes Indian education statistics from a JSON file, grouping entries by region and subregion. The example uses d3.v3 with the d3.layout.treemap API and SVG rendering, implementing custom recursive layout and accumulate functions. Click transitions animate zooming between hierarchy levels, with an orange breadcrumb bar showing the current path and enabling navigation back to parent nodes.

Zoomable Treemap

A zoomable treemap displays a hierarchical dataset as nested rectangles, with area encoding each node’s value. Users click a cell to zoom in and explore its children, or click the top to zoom back out. Built with d3.treemap, a custom tiling function, and d3.scaleLinear for positioning. Zoom transitions animate both SVG groups and their coordinates. Data comes from the flare-2.json file, rendered as animated SVG with click-driven navigation.

Zoomable Treemap

This zoomable treemap visualizes UK Home Office flight data from 2011, showing hierarchical relationships between destinations, suppliers, and ticket classes. Built with D3 v2 and rendered as an SVG with smooth zoom animations, the treemap uses nested rectangles sized by paid fare amounts, with color encoding categories. Users can click to zoom between hierarchy levels. The data is loaded from a CSV and transformed using d3.nest, while the custom layout function optimizes the treemap for the current zoom state, enabling fluid transitions as users navigate the data.

Zoomable Treemap

This zoomable treemap visualizes global mortality data by cause, using nested rectangles whose areas encode death tolls. Users can click any rectangle to drill into subcategories—from broad causes like famine or natural disasters down to individual events. Built with D3 v2, the visualization reads a CSV, nests it hierarchically, and animates smooth zoom transitions between levels. The color and size of each tile encode the hierarchical data structure and relative magnitude of deaths.

Zoomable Treemap

This zoomable treemap visualizes global cause-of-death data, using a CSV dataset that records death counts across four nested levels: broad cause, subcause, and specific disease. Built with D3 v2 and rendered as SVG, the treemap encodes hierarchy and quantity through rectangular area and color. Users can click to zoom between levels, and the visualization animates smoothly during transitions. The root node aggregates over 800 million deaths, with branches for Disease, Non-communicable, health complications, and Cancer, allowing exploration from global causes down to individual conditions. The example uses a custom data-reshaping function to transform the CSV into the nested structure the treemap layout requires, and includes CSS styling for interactive hover states and text labels.

Treemap

This treemap visualizes hierarchical data from a CSV file, showing production values for countries grouped under parent categories as nested rectangles. The example uses D3.js v6 with a CSV-parsed hierarchy, stratifying the data via `d3.stratify()` and computing rectangle positions with `d3.treemap()`. Rectangles are rendered as SVG elements with a teal fill and black stroke, while country labels appear in white text within each cell. The layout uses a fixed canvas size with padding between nodes, and styling comes from the included CSS.
