This treemap visualizes hierarchical data, such as the flare.json dataset, using nested rectangles to represent size values, with an option to re-sort by count. It shows an interactive animation that smoothly transitions between these two aggregation modes. Built with D3.js v4, the code uses `d3.treemap`, `d3.treemapResquarify`, and `d3.hierarchy` to process data, while SVG rendering and `d3.transition()` handle the animated updates. The example also includes a color scale from `d3.schemeCategory20` for visual distinction.

AI-generated description

An example of porting a work from bl.ocks.org into VizHub. This is a direct port of Mike Bostock’s Block: Treemap, modified only to split into separate files, and to fit in the space available.

Treemap from bl.ocks.org

A treemap visualization displays the hierarchical structure of the flare.json dataset, with nested rectangles sized by either node size or leaf count. The interactive chart allows toggling between these two aggregation modes via radio buttons, triggering a smooth animated transition. Built with D3 v4, the visualization uses `d3.treemap`, `d3.hierarchy`, and `d3.scaleOrdinal` for coloring, rendering SVG cells with clipped text labels and tooltips.

Treemap from bl.ocks.org

A treemap visualizes the hierarchical structure of the Flare data set, with nested rectangles representing leaves sized by their numeric value. The visualization renders using SVG elements and includes an animated transition between two aggregation modes: "Size" and "Count". Built with D3 v4, the code uses `d3.treemap` with the `d3.treemapResquarify` tiling algorithm, `d3.hierarchy`, `d3.scaleOrdinal` for color, and `d3.interpolateRgb` for fading. A 2-second timer automatically triggers the mode change.

Treemap from bl.ocks.org

A treemap visualizes the hierarchical structure of the Flare data set, with nested rectangles whose areas encode either the size or count of each node. The visualization uses D3’s `d3.treemap` layout with `d3.treemapResquarify` tiling, rendering the hierarchy as an SVG. Animated transitions smoothly reshape the treemap when toggling between the "Size" and "Count" aggregation modes. The color scheme is derived from `d3.schemeCategory20`, and the tooltip displays the node’s path and numerical value.

Treemap from bl.ocks.org

This treemap visualizes the hierarchical structure of the Flare data set, encoding each leaf node’s size by its rectangular area and grouping related categories by color. The view toggles between summing node values by size or by count, with animated transitions updating the layout over 750 milliseconds. Built with D3 v4, the example uses `d3.treemap`, `d3.hierarchy`, `d3.scaleOrdinal`, and `d3.treemapResquarify`, rendering the hierarchy as SVG rects and text elements with clip paths.

Treemap from bl.ocks.org

This treemap shows the hierarchical structure of the Flare data set, with nested rectangles sized by either data value or leaf count. Rectangles are colored by parent category and labeled with truncated names. The visualization transitions between the two sizing modes over 750 milliseconds after a two-second delay, using the `d3.treemap` layout with a resquarify tiling function. The implementation uses D3.js v4 to render SVG elements, with text clipping via `clipPath` and an ordinal color scale based on `d3.schemeCategory20`.

This treemap visualizes the hierarchical structure of the Flare data set, using nested rectangles whose areas encode each leaf’s size value. Users can toggle between summing by size or by count via radio buttons, which triggers a smooth 750ms transition of the rectangles. The visualization is built with D3 v4, using `d3.treemap` with the resquarify tiling function, `d3.hierarchy`, and `d3.scaleOrdinal` for color coding by parent category. The SVG rendering includes clip-paths for text labels and tooltip titles on each leaf.

Treemap from bl.ocks.org

A hierarchical treemap displays the flare dataset, showing nested file sizes and counts as colored, labeled rectangles. The visualization uses `d3.treemap` with the `d3.treemapResquarify` tile method, rendering SVG rectangles and text with mouse-over titles. Radio buttons switch between summing by file size and by node count, triggering a 750ms `transition` that animates rectangle positions and dimensions. D3 v4 and `d3.scaleOrdinal` with `d3.schemeCategory20` color the cells.

This example shows a treemap visualization of the Flare data hierarchy, where each rectangle’s size corresponds to the value of a leaf node, and color encodes the parent category. It uses `d3.treemap` with the `d3.treemapResquarify` tiling algorithm to compute rectangles within a 960x480 SVG canvas. The visualization animates between two aggregation modes (by size and by count) using a `transition` on cell transforms over 750 milliseconds, with a `d3.timeout` automating the mode switch after two seconds. Text labels are clipped and wrapped within each cell.
