This example demonstrates an interactive zoom on a time-series area chart of S&P 500 monthly closing prices from 2000 to 2010. Initially, the view animates from a transformed scale to a default extent over two years, using `d3.zoom()` and `d3.zoomIdentity` to rescale the time axis. The chart is rendered as an SVG, with a clipped area path and axes updated during the zoom transition. Data is loaded from `sp500.csv`, and the zoom is implemented with a 1.5-second transition.

Understanding the zoom on d3.js

This example demonstrates interactive zooming and panning on a time-series area chart of S&P 500 monthly closing prices. The visualization uses d3.zoom with scale and translate extents to constrain navigation, updating the area path and x-axis via the transform’s `rescaleX` method during the `zoom` event. Animated intro zoom transitions from January 2003 to January 2004. Data comes from a local CSV file, rendered as an SVG area with `d3.area` and `curveMonotoneX`.

Zoom to Domain

A line chart of S&P 500 monthly prices from 2000 to 2010 plays an introductory zoom animation, smoothly transitioning from the full dataset to a one-year window centered on 2003. The area chart uses an SVG path with a clip-path. Built with D3 v4, it applies `d3.zoom` and `d3.zoomIdentity` to programmatically rescale the time axis via `rescaleX`, updating the area and x-axis in the `zoom` event handler.

Fork of Understanding the zoom on d3.js

A fork of Mike Bostock’s zoom example, this visualization displays monthly S&P 500 closing prices as a blue area chart. An initial animated transition zooms into the data range from 2003–2004, and users can continue panning and zooming interactively. The code uses d3.zoom with scaleExtent and translateExtent, d3.area with curveMonotoneX, and d3.axisBottom for the time axis, rendering everything as SVG.

Zoom + Pan

This example demonstrates how to pan and zoom a chart using D3.js v3. It renders an SVG with axes and a filled background rectangle, using linear scales for the x- and y- dimensions. The `d3.behavior.zoom` API links the zoom behavior to the scales, allowing mouse wheel and drag interactions to rescale the axes. When zooming occurs, the axes are redrawn to reflect the updated scale ranges. The code sets a zoom scale extent between 1 and 32, and uses `d3.svg.axis` to produce the tick marks and grid lines.

Brush & Zoom

This example shows a focus and context view of the Standard & Poor’s 500 stock index over time, with a large area chart on the top and a smaller overview below. A colored brush in the context pane selects a date range, while a transparent rectangular overlay on the focus pane enables direct zooming and panning via the `d3.zoom` API; both interactions synchronize the visible data domain. The code combines `d3.brushX` with `d3.zoom`, and uses `d3.scaleTime`, `d3.axisBottom`, and `d3.area` to render the monthly price data from the CSV file as scalable vector graphics (SVG).

D3 Zoom

A D3 zoom interface demonstrates interactive panning and scaling within an SVG coordinate system. A single green circle, positioned through linear scales, responds to mouse wheel and drag gestures that trigger the `d3.zoom` behavior. The example simultaneously updates axis tick marks via `transform.rescaleX` and `rescaleY`, while displaying the current translation values and zoom multiplier in separate HTML divs. The visualization renders with SVG elements, using `d3.axisBottom`, `d3.axisLeft`, and `d3.scaleLinear` to maintain spatial mapping during the zoom transform.

D3 Zoom

This example demonstrates interactive zooming and panning on a scatterplot of 100 randomly positioned points. Users can scroll to zoom in and out within a scale extent of 0.5x to 4x, or click and drag to pan across the full-window SVG canvas. The visualization uses d3.zoom to attach zoom behavior to the root SVG element and applies the transform directly to that element’s `transform` attribute during the zoom event. Data is generated randomly with the `makeData` utility, and circles are bound and updated using D3’s data join pattern.

Understanding of Zoom behavior

This example demonstrates a zoom behavior on a map populated with 500 randomly placed symbols, each rendered as a distinct path. When the user zooms, the symbols scale their area by the square of the zoom factor, while the stroke width is adjusted to remain visually constant. The code uses d3.zoom to manage the zoom transform, accessing the `d3.event.transform` to read the scale factor `k`. It redraws the `d` attribute of each path to adjust symbol size and sets `stroke-width` to `1/t.k` to maintain consistent border width.
