A simple brush interface displays a numeric range selection on an empty plot with an X axis. Dragging the brush updates a text label showing the current extent values. The example uses D3 version 3.5.5 with `d3.svg.brush` and `d3.scale.linear`, rendering via SVG. Data consists of 800 random numbers generated with `Math.random`, though they are not visualized.

Brush Slider Test

This example demonstrates a brush-style slider that filters a numeric range, displaying the selected minimum and maximum values as text above the axis. Rendered as SVG, it uses D3 v4’s `d3.brushX()` to create the interactive selection and `d3.brushSelection` to read the current range. The x-axis is generated with `d3.axisBottom` and a linear scale, with the brush initially positioned between 20 and 50 via `brush.move`. The code also notes key API changes from D3 v3 to v4, such as handling brush extents on the brushed element.

Brush I

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.

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.

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.

d3-brush example

A minimal interactive brush demonstration renders a 400 by 400 SVG rectangle, where the user drags to select a rectangular region. The example uses the d3-brush API from D3 version 4 to track selection coordinates, logging the starting and ending positions to the browser console during brushing and reporting the absence of a selection when the brush is cleared. The code defines the brush extent to match the full drawing area and attaches start, brush, and end event handlers.

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.

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 d3v4 II

This example demonstrates a D3 v4 brush with custom resize handles on a scatterplot of 800 random points. The brush selects a horizontal range along the x-axis, highlighting points within the selection by adding an “active” class. Custom path-based handles replace the default brush edges, using a `brushResizePath` function to draw arrow-like grips. The code uses `d3.brushX`, `d3.axisBottom`, and `d3.scaleLinear`, with the brush’s `start`, `brush`, and `end` events driving the highlighting logic via `d3.event.selection`.
