Maps are used so widely in web design and they are usually expected to be interactive when presenting data. It can be the branches of an international company, statistics about countries or just destinations to visualize.
When building any map-related applications, there are many popular providers to select from like Google Maps or Bing Maps and they provide APIs for integration. However, using an open source engine and the ability to switch providers anytime offers more freedom + flexibility.
For this roundup we have chosen some of the Best JavaScript Libraries for creating interactive maps for your web applications. Following libraries provides myriad of functions and features that help developers to create complex maps easily and quickly. Please share your feedback by posting a comment below.
1. JavaScript Mapping (JSMapping)
Native SVG maps with a complete highly tuned map set for all countries in the world including state and province boundaries. Built in chart layers for bubble, point, line and thematic choropleth maps. View the map gallery to learn more. Quick and simple installation allows you to generate your first map in minutes.
2. GMaps
GMaps.js allows you to use the potential of Google Maps in a simple way. No more extensive documentation or large amount of code. GMaps is compatible with JSON formatted data which you can utilize to integrate your map with a particular app, like Foursquare.
3. jHere
With jHERE, you can easily add interactive maps to your website. In only 4KB, you get a powerful map API, highly customizable markers, event handling and info bubbles. Bonus features are KML support and data visualization via heatmaps.
4. Cesium
Cesium, a WebGL-powered JavaScript mapping library, offers just that by being provider-agnostic. It has support for 3 different views: 3D globe, 2D map, and 2.5D Columbus View where transitioning from one to another is just a line of code. Drawing any type of shapes, highlighting specific regions and interacting with the map using mouse or touch is pretty easy. Cesium comes as a single JS file and work in all major browsers including mobile.
5. Kartograph
Kartograph is a framework for creating interactive maps without any mapping provider (like Google Maps). If you already have the SVG data (for ex: any drawing can be converted to SVG with Adobe Illustrator), only the JavaScript library can help too. The JS library uses jQuery + Raphaël, outputs can be styled with CSS and a very good documentation is provided.
6. D3.js
D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG and CSS. D3’s emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation.
7. DataMaps
DataMaps is a script to display any data interactively and beautifully inside maps. It comes with ready-to-use maps for world map with countries, USA with states and a combined one. The map data is stored as JSON and any custom maps can be created by following the structure. DataMaps makes use of D3, Backbone + Underscore and comes as a jQuery plugin (or a as a standalone Backbone view).
8. Stately
Stately is JavaScript library that is developed to generate US maps. The library is comparably lightweight considering that you can add interactive elements on top of your generated maps.
9. OSM Buildings
OSM Buildings is a JavaScript library that enables us to create a similar functionality using any mapping provider. The library uses Leaflet mapping engine and HTML5 canvas (rather than WebGL) and requires the geometry data of the area to be visualized. There are various free sources for such data and the library can be handy when creating such custom visualizations for a limited area.
10. Leaflet
Leaflet is a modern open-source JavaScript library for mobile-friendly interactive maps. Leaflet is designed with simplicity, performance and usability in mind. It works efficiently across all major desktop and mobile platforms out of the box, taking advantage of HTML5 and CSS3 on modern browsers while still being accessible on older ones. It can be extended with many plugins, has a easy to use and well-documented API and a simple, readable source code.
11. PolyMaps
Polymaps is a free JavaScript library for creating dynamic and interactive maps. Besides the usual cartography from OpenStreetMap, CloudMade, Bing, etc., itworks with image-based and vector-tiled maps by providing a quick display of multi-zoom datasets over maps, and supports a variety of visual presentations. As Polymaps can load data at a full range of scales, it’s a good fit for showing information from country level on down to states, cities, neighborhoods, and individual streets.
12. Cartographer.JS
Cartographer is a JavaScript library for creating thematic maps on Google Maps which supports custom styling. It is only a one JavaScript file that relies on the powerful Raphael.js vector-graphics library. The areas on maps are mentioned as latitudes or regions (depending on the type) which mean no hacking or manual calculations. Every visualization type comes with different options like colors, opacity, stroke & more.
13. MaPlace.js
Maplace.js is a small Google Maps Javascript plugin for jQuery that helps you to embed Google Maps into your website, quickly create markers and controls menu for the locations on map. It requires jQuery and Google Maps API v3 so you need to have both in your page.It supports markers and custom icons, zoom level and custom controls menu. It is released under the MIT license.
14. amMap
amMap is a tool that you can use to easily add interactive map functionality to your web pages and JavaScript-based applications. You can use this tool to show locations of your offices, routes of your journeys, create your distributor map, etc. Photos or illustrations can be used as layers and backgrounds of maps, so you can make different presentations, e-learning tools and more.
15. SpryMap
SpryMap is a super lightweight (2.8 KB), dependency free Javascript widget that turns any HTML element into a Google Maps-like click and drag window. SpryMap is released under the creative commons license, essentially you’re free to use it and adapt it for any personal or commercial purposes.
