A brushable scatterplot displays 300 randomly generated points. A horizontal brush initially selects a range, highlighting points within it in red with a brown stroke. The example uses d3.brushX to define the brush and handles the brush event to update the selection state. Clicking re-centers the brush using a fixed width, demonstrating interactive selection on an SVG rendered with d3.scaleLinear and d3.axisBottom.

Click-to-Recenter Brush II

A scatterplot of 800 points uses a horizontal brush to highlight selections in red. Clicking the background recenters the brush around the cursor, using `d3.brushX` with a fixed width, while a `brushended` handler snaps the brush extent to integer values on the x-axis via `Math.round` and `brush.move`. The SVG rendering uses `d3.scaleLinear` for axes and a transition animation on brush movement.

Click to Select All

A scatterplot displays 800 randomly generated points positioned across a linear x-axis and normally distributed y-values. Clicking and dragging outside the existing selection normally creates a new brush, but this modified behavior selects all points instead. The visualization uses D3 v4’s `d3.brushX` to handle brushing, `d3.scaleLinear` for axes, and SVG circles with red fill and brown stroke for selected items. A transition animates the brush movement when the user activates the select-all interaction.

Brush Handles

This example shows a scatterplot of 800 random points on a linear x-scale, with a draggable d3.brushX selection. Custom semicircular path handles are attached to the brush’s west and east edges, letting users resize the selection by dragging these visible arcs instead of the invisible brush boundary. The brushmoved handler updates the handle positions and highlights points inside the selected range. It uses d3.brushX, d3.axisBottom, d3.randomNormal, and d3.arc for the handle shapes, rendering to SVG.

The Brush

A line chart displays randomly generated data points, with a transparent red brush overlay that highlights a selected data point and its corresponding value label. Dragging the brush across the chart triggers the highlighting, which animates smoothly. Built with D3 v3, the visualization uses SVG rendering, `d3.svg.brush()` for selection, and `d3.svg.axis()` for gridlines and ticks, with all data generated randomly in the browser.

Scatter plot brushing

This example demonstrates interactive brushing on a scatter plot, where users can drag a rectangular selection to highlight points within that region in orange while dimming others remain blue. The visualization uses 300 randomly generated data points from a normal distribution, rendered as SVG circles with axes. The brushing interaction is implemented using d3.brush, with the brushed event updating circle fills based on the selection bounds, while brushended resets the colors with a smooth transition when the brush is cleared. The code uses d3.scaleLinear for positioning and d3.axisBottom/axisLeft for axes.

Brushing

This example demonstrates interactive brushing on a small scatter plot of weight and height data from a CSV file. Users drag a rectangular brush region to highlight data points, turning selected circles red and unselected ones blue. The visualization uses D3 v6 with an SVG rendering, a linear scale for both axes, and d3.brush to manage the selection. Points are positioned using transitions and axes are rendered with d3.axisLeft and d3.axisBottom.

Brush Snapping III

This example shows three clusters of 300 normally distributed points each, colored by cluster using `d3.schemeCategory10`, with visible x- and y-axes. A horizontal brush, created with `d3.brushX`, snaps its selection to integer coordinates on the x-axis. During a brush drag, the code maps the selection back to data space, rounds the values, and uses `d3.event.target.move` to reposition the brush, ensuring the selection always covers a complete unit interval.

Click-to-Recenter Brush

A click-to-recenter brush demonstrates a modified brushing interaction for scatterplot data. By default, dragging outside an existing brush selection creates a new selection; here, it instead repositions the brush so it remains centered on the pointer. The chart plots 800 random points with `d3.randomUniform` and `d3.randomNormal`, rendered as SVG circles with a linear x-scale. The customization uses `d3.brushX`, replacing the overlay’s interaction type with “selection” and adding a `mousedown` handler that calls `brush.move` to recenter before brushing.
