This example demonstrates automatically positioned floating labels for data points in a scatterplot. The labels are placed using a D3 force-layout, with each label connected to its anchor point via a link and adjusted to avoid overlaps based on user-controlled charge. The visualization updates in real time as new data points are added or the correlation between variables is adjusted. The code uses `d3.layout.force` from D3 v2, custom label positioning logic (`force_labels.js`), and SVG elements like `circle`, `text`, `line`, and `g` to render the plot and labels.

Force Layout with labels on edges

This visualization demonstrates a force-directed graph with labeled edges, using d3.layout.force to position ten named nodes and thirteen links. Edge labels automatically flip 180 degrees when the target node moves left of the source, keeping text readable, while arrowheads mark link direction. The code renders SVG circles, lines, and text paths, updating positions each tick via the force layout’s event handler.

Force based label placement

Two force-directed layouts run simultaneously: one positions graph nodes and edges from randomly generated links, while a second governs label anchors that orbit each node at a fixed distance and repel one another to prevent overlap. Labels on the right align left, labels on the left align right, with interpolation in between. The code uses d3.layout.force for both simulations, d3.select, SVG text bounding boxes via getBBox, and manual transform updates on each tick.

zoomable, draggable force layout with labels

This interactive force-directed graph displays ten labeled nodes (A through J) connected by links, with Font Awesome icons as labels overlaid on colored circles. The layout uses D3 v4’s `d3.forceSimulation` for physics-based positioning, combined with `d3.drag` for node dragging and `d3.zoom` for canvas zoom and pan. Node positions are bounded within the SVG viewport, and an HTML slider controller adjusts an external value. The black background, custom fonts, and Bootstrap controls frame the visualization, which reads node and edge data from a local `data.json` file.

force directed text fit labels

This example shows a hierarchical dataset rendered as a force-directed graph, where parent nodes are connected to child nodes by lines, and each leaf node displays its label text inside a circle sized by its value. The visualization uses d3.forceSimulation with forces for link distance, charge, centering, and collision, while text is fit to each circle by computing a font size based on the circle’s radius and the text length. Nodes and links are drawn as SVG elements, with data loaded from a CSV file via d3.csv and a stratify layout, and labels are added for leaves using underscore.js.

ZTLCSTN

This example visualizes a graph dataset with force-directed layout, rendering nodes as circles with labels and links as connecting lines within an SVG canvas. It uses D3.js v6 with the `d3.forceSimulation` API for physics-based positioning, incorporating forces like link attraction, many-body repulsion, and centering, while enabling interactive drag and zoom through `d3.drag` and `d3.zoom` behaviors. The graph data is prepared by mapping coordinate fields, filtering inactive or broken links, and then animated in real-time as the simulation ticks update node and link positions.

force directed text fit done

A force-directed layout arranges a hierarchical dataset as a bubble chart, with circle size proportional to each node’s value and text labels fitted inside. Nodes cluster by parent, while lines show parent–child links. The simulation uses `d3.forceSimulation` with `forceLink`, `forceManyBody`, `forceCenter`, and `forceCollide`. Labels are rendered as SVG text with font sizes computed per tick and node radius. Data loads from a CSV via `d3.csv`, and colors come from `d3.scaleOrdinal(d3.schemeCategory10)`.

ForceLayout - maintain x-position of nodes

This example visualizes the distribution of 150 French word stems along the x-axis based on a trend value, with each circle’s horizontal position fixed while vertical positions resolve through force simulation. The D3.js v3 force layout uses custom constraints to lock each node’s x-coordinate, allowing circles to stack vertically for easier hover inspection. Tooltips display the stem, rank, and trend value on mouseover, with a data-gui control to quadruple the number of points. The chart renders as animated SVG, reusing bounded-force techniques from mbostock and bjtucker.

force test I

This animated SVG visualization uses D3’s force layout to cluster 99 circles into four labeled category groups. The circles drift toward category centers based on their assigned category, with charges pulling them apart, while the labels and target centers shift every five seconds between original, four-category, and two-category layouts. The code explicitly defines category centers and calls `d3.layout.force` with a custom `tick` handler and `charge` function. Data is generated randomly, and rendering relies on SVG `circle` and `text` elements manipulated via D3 selections.
