Description
This project provides a plugin for zooming to arbitrary coordinates on a D3/Datamaps svg.
Getting Started
Git
Clone the project via git
. Dependencies can be installed with yarn install
,
and running grunt
will build the source code. The original and minified
versions will be present in the build
directory.
Yarn
Run yarn install datamaps-zoomto
. The source will then be located in
node_modules/datamaps-zoomto/build
.
Sample Usage
// Create a Datamap instancevar dm = element: document; // Setup the options for the zoom (defaults given)var zoomOpts = scaleFactor: 1 // The amount to zoom center: lat: <the center of your original map> // latitude of the point to which you wish to zoom lng: <the center of your orignal map> // longitude of the point to which you wish to zoom // NOTE: You cannot specify lat without lng or lng without lat. It's all or nothing. transition: duration: 1000 // milliseconds { // Called after zoomto completes. Bound to the Datamaps instance. // Passes one argument, zoomData. // zoomData = { // translate: { x: <number>, y: <number> }, // scale: <number> // } // no-op by default }; // perform the zoomdm; // Of course, using the default zoom will not actually zoom due to a 1:1 scale// and the center of the map not changing.

Using with Webpack
It is also pretty easy to use this plugin in a Webpack bundle. See
the webpack-example
directory for details.
const Datamaps = ;; var dm = element: document; dm; // or using ES6 import syntax ;; var dm = element: document; dm; dm;
