Overview

The JavaScript Maps Library control is ideal for rendering maps from GeoJSON data or other map providers like OpenStreetMap, Google Maps, Bing Maps, etc. Its rich feature set includes markers, labels, bubbles, navigation lines, legends, tooltips, zooming, panning, drill down, and more.


GeoJSON layer

Bind GeoJSON data to the maps to render any geometric shape in SVG (Scalable Vector Graphics) for data visualization of shapes. For example, render the world map or US map and customize it to the desired look using built-in options in the JavaScript Maps control. Add any number of layers to the maps.

JavaScript Maps is rendered with geometry type over OSM map

Geometry types

GeoJSON data contains geometry objects with properties such as geometry types and coordinates. The geometry types are the values present in the geometry objects of the GeoJSON data that specify the type of shape to be rendered, along with the coordinates that help to draw the shape’s boundary line. Polygon, MultiPolygon, LineString, MultiLineString, Point, MultiPoint, and GeometryCollection are the supported geometry types.


Geo-imagery visuals

Built-in support for external geospatial imagery services, such as Bing Maps and OpenStreetMap, is used to visualize satellite, aerial, and street maps, or other kinds of imagery tiles without any external shape inputs. Apart from Bing Maps and OpenStreetMap, users can also render maps from various map providers, for example, Google Maps Tile API, TomTom, Mapbox, Esri’s ArcGIS, etc. By using these external services, map data can be located easily.

JavaScript Maps with multiple layers

Multi-layers

Using sublayer, a JavaScript Map can be created with multiple geometric layers in a single view. For example, render additional geographic features of a country such as rivers, valleys, and more as sublayer. You can also drill each layer.


Marker

Denote a place with symbols or mark messages at the desired latitude and longitude on a map using markers. For example, indicate a particular place on the US map using a balloon marker shape. Also, place any HTML element as a marker and add multiple markers to the map.

JavaScript Maps is rendered with marker clustering option

Marker clustering

Display multiple markers in the same location by clustering the markers overlapping one another. For example, use markers to indicate the top 50 cities in the world. If a marker overlaps another, it will be clustered, and the total number of markers will be displayed over the cluster.


Data labels

Data labels on the map provide identification for the shapes by displaying their names. Trim or hide the labels at intersections with other labels and when they exceed shape bounds.

JavaScript Maps is rendered with multiple bubbles

Bubble

Create a simple JavaScript Map with bubbles to represent additional information about shapes such as population density, land area, and more. Bubbles are rendered with various magnitudes and colors based on the underlying data values of the shape.


Denote flight routes or ship routes on a geographic map between two places. These connector lines link points on a map and can also be curved.

Color mapping

Categorize the shapes on a map by customizing their color based on the underlying values. The JavaScript Maps Library control supports three types of color mapping: range color mapping, equal color mapping and desaturation color mapping.

Range color mapping is applied for the shapes in JavaScript Maps

Range color mapping

Apply colors to the shapes by comparing their values with a desired numeric range. For example, apply colors to the states in the US based on population density.

Equal color mapping is applied for the shapes in JavaScript Maps

Equal color mapping

Differentiate a shape’s fill based on its underlying values and colors, using equal color mapping. For example, apply colors to the states in the US based on a winning candidate.

Desaturation color mapping is applied for the shapes in JavaScript Maps

Desaturation color mapping

Change the opacity of the shapes by comparing their values with a desired numeric range. Minimum and maximum opacity of the shapes can be customized.

Desaturation color mapping with multiple colors are applied for the shapes in JavaScript Maps

Desaturation with multiple colors

Apply multiple colors to the shape from a gradient by comparing their values with a desired numeric range. Any number of colors can be specified for creating the gradient.


Legend

Legends provide valuable information for interpreting the map with various colors, shapes, or other identifiers based on data and application needs. Interactive JavaScript Maps Library control supports two types of legends: Default and Interactive.

JavaScript Maps is rendered with default legend items

Default

A map with a legend contains swatches of symbols with descriptions to denote the categories of shapes.

JavaScript Maps is rendered with interactive legend

Interactive

Use a JavaScript Map with an interactive legend to find the range of an underlying shape’s value on mouse hover.


Zooming and panning

Zoom the JavaScript Map for close-up analysis by pinching the map, scrolling the mouse wheel, clicking the shapes, or by using zooming toolbar; and pan the map for easy navigation across regions. Also change the zoom level of the initial rendering.

Zooming and panning is enabled in the JavaScript Maps


Displays a tooltip on moving mouse over the JavaScript Maps

Tooltip

The tooltip displays details about the shape value on mouse hover. Tooltips are also displayed for markers and bubbles on a map.


Drill-down

Drill-down the rendered JavaScript Maps to display a different shape data located on another layer. For example, in the initial layer render the world map and on clicking a particular continent, render it separately on another layer.

JavaScript Maps is rendered with multiple layers and enabled drilldown option


Particular shape is selected in the rendered JavaScript Maps

Selection and highlight

Select a particular shape on mouse click or highlight on mouse hover to bring the focus to the other shapes on a map.


Custom shapes

Create a JavaScript Map with custom shapes by rendering personalized GeoJSON data to indicate building infrastructure, points of interest, flight/bus seat arrangement, cricket stadium, and more.

Bus seat selection is simulated in the JavaScript Maps


JavaScript Maps is rendered with annotation which has direction compass image

Annotation

Display any HTML element as an annotation at a specific point of interest on a map. For example, place a direction compass image on the map using annotation. Also add multiple annotations to a map.


Projection

Change the projection of the default rendering map based on the need. The HTML5 JavaScript Maps control supports various types of projections namely, Mercator, Rectangular, Miller, Eckert3, Eckert5, Eckert6, and Winkel3.


State persistence with JavaScript Maps Library

State persistence

State persistence allows the Maps component to maintain state by storing the most recent model value in browser cookies. When the appropriate setting is enabled, some of the Maps component model values are preserved even after the page is refreshed.


Title and subtitle

Add title and subtitle to visualize additional information on the Maps. Fonts and alignment of the title and subtitle can also be customized.

JavaScript Maps is rendered with title and subtitle


JavaScript Maps is rendered with customized appearance

Appearance

Customize the look and feel of a JavaScript Map by changing the fill color, background, border, and opacity of shapes. Almost all the elements in the JavaScript Maps are customizable. This control also provides built-in palettes with customizable options, by default.


Exporting

Export or print the rendered JavaScript Maps to save a local copy for further use.

Export JavaScript Maps illustration
