Panning and zooming are popular interaction techniques which let the user focus on a region of interest by restricting the view. It is easy to learn due to direct manipulation: click-and-drag to pan (translate), spin the wheel to zoom (scale), or use touch. Panning and zooming are widely used in web-based mapping, but can also be used with visualizations such as time-series and scatterplots.
The zoom behavior implemented by d3-zoom is a convenient but flexible abstraction for enabling pan-and-zoom on selections. It handles a surprising variety of input events and browser quirks. The zoom behavior is agnostic about the DOM, so you can use it with SVG, HTML or Canvas.
