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.

Scatter plot with zoom

This scatter plot visualizes 300 normally distributed data points and supports interactive zooming through a brushed region. Users can drag to select a rectangular area, which triggers a smooth animated transition that rescales the x and y axes to focus on the selected points. Double-clicking outside the brushed area resets the view to the full dataset. The implementation uses D3 v4’s `d3.brush` for selection handling, `d3.scaleLinear` for coordinate mapping, and `transition.attr` to animate the circles’ positions. The axes are updated via `d3.axisBottom` and `d3.axisLeft`, with a clip path preventing points from spilling outside the plotting area.

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.

Brushing Circles with D3-Brush

This example demonstrates interactive brushing on a scatterplot of six circles, where dragging a rectangular selection highlights overlapping data points. It shows how a brush can filter or emphasize specific marks in a visualization. The implementation uses D3’s `brush` module, with a `brush` event listener that checks each circle’s coordinates against the selection bounds to update a `highlightedSet` in the state. Circle styling (stroke, opacity) responds to the highlighted set, and the `end` event clears highlights when the brush is dismissed. The rendering uses SVG elements via D3’s `select` and `join` pattern.

Untitled

This example demonstrates a basic scatter plot where users can brush-select points to highlight them in red. It uses D3 version 7 to generate 200 random data points and render them as SVG circles. The brushing interaction is handled by `d3.brush()`, which triggers a callback that updates the fill color of selected points. The code uses `d3.select()` and the `.join()` API to efficiently manage the circle elements.

Brush & Zoom II

This example demonstrates how brushing a scatterplot with d3.brush zooms to the selected region, while double-clicking resets the view. The code generates 900 random points in three gaussian clusters, rendering them as colored circles and using a linear scale to map coordinates. The brush’s `end` event updates the x and y domains, then animates the axes and points via `transition`. A 350ms idle timeout distinguishes a brush clear from a double-click reset.

Brush Handles

This example shows an 800-point scatterplot with a draggable, visible brush handle range selection. The brush is rendered as two semi-circular handles on either side of the selection extent, which the user can drag to resize the range. The code extends `d3.brushX` with custom `path` elements and uses `d3.arc` to define their shapes. When the brush moves, a `brushmoved` function updates the handle positions and highlights the selected circles by toggling an "active" class, which changes their fill opacity.

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.
