EasyPZ

Use this Javascript library to make your web visualization interactive via pan and zoom, for mobile and desktop!

EasyPZ supports many interactions for panning and zooming, including wheel, pinch, double click, hold, brush, rub, and dynamic zoom, panning methods including default, flick, and many variations.

Many examples can be found at easypz.io, including examples using d3, and examples that use canvas instead of SVG. Examples from the d3 gallery that just magically turn into navigatable visualizations without a single line of code can be found at demos.easypz.io.

Instructions on how to use EasyPZ, explanations for the many options, as well as how to extend EasyPZ with your own pan or zoom method, can be found in the Wiki!
