Class Summary

Class	Description
BubbleMapChart	A Bubble Map, as known as Proportional Symbol is used to render maps with dots that are scaled according to some numerical value. It is based on a regular bubble chart where the positioning is done using latitude and longitude to create a legend for the different radi.
BubbleMapDataPoint	Used for BubbleMap data sets to set the data to render. A data has to have a latitude and longitude properties and a value property containing the value for the coloring.
BubbleMapDataPoint.BubbleMapDataPointFactory	Creates BubbleMapDataPoint form a NativeObject.
BubbleMapDataset	It is a BubbleDataset with additional options for bubble map charts.
BubbleMapOptions	Specific options for bubble map chart.
ChoroplethChart	A choropleth chart is used to render maps with the area filled according to some numerical value.
ChoroplethDataPoint	Used for GEO data sets to set the data to render. A GEO data has to have a feature property containing the feature to render and a value property containing the value for the coloring.
ChoroplethDataPoint.ChoroplethDataPointFactory	Creates ChoroplethDataPoint form a NativeObject.
ChoroplethDataset	The choropleth data set allows a region definition (by Feature) and specific value to be specified.
ChoroplethOptions	Specific options for choropleth chart.
ColorAxis	The coloring of the nodes will be done with a special color scale. Provides the elements, as colored legend, which can provide the how the values are distributed on map.
ColorLogarithmicAxis	The coloring of the nodes will be done with a special color scale, for logarithmic data. Provides the elements, as colored legend, which can provide the how the values are distributed on map.
Coordinates	Contains the latitude and longitude, calculated by BaseGeoChart.projectionInvert(CoordinatesPoint) and BaseGeoChart.projectionInvert(double, double).
CoordinatesPoint	Contains the coordinates X and Y on the canvas, calculated by BaseGeoChart.projection(Coordinates) and BaseGeoChart.projection(double, double).
DataPointCenter	This class enables the capability to specify the coordinates where the tooltip should appear.
Feature	Represents the region definition with all properties and geometries needed to draw the region.
GeoFeatureElement	Calling some methods on your chart instance passing an argument of an event, will return the elements at the event position. The geoFeature elements are mapped by this object.
GeoFeatureElementOptions	The styling of the new element GeoFeatureElementOptions is based on Bar element with some additional options for the outline and graticule.
GeoUtil	Utility to manage TopoJson definitions. TopoJson is an extension of GeoJSON that encodes topology. Rather than representing geometries discretely, geometries in TopoJson files are stitched together from shared line segments called arc. PAY ATTENTION CHARBA doesn't include any TopoJSON files itself. Some useful resources I found so far: US map: https://www.npmjs.com/package/us-atlas World map: https://www.npmjs.com/package/world-atlas TopoJson collection: https://github.com/deldersveld/topojson
Graticule	The network of intersecting lines of latitude and longitude is called the graticule. It is imaginary on the earth, of course, but is drawn on globes and maps for reference. The graticule of latitude and longitude lines is an angular measurement system.
Legend	Legend configuration for GEO chart scale.
Margin	Defines the margin pixels for legend such that it doesn't stick to the edge of the chart .
Padding
PositionPoint	This object is wrapping the native java script object to provide the position of the legend.
ProjectionAxis	A map projection is a way to flatten a globe's surface into a plane in order to make a map. This requires a systematic transformation of the latitudes and longitudes of locations from the surface of the globe into locations on a plane. This is the scale which is managing the map projection.
SizeAxis	The scale is used to map the values to symbol radius size. Provides the elements, as colored legend, which can provide the how the values are distributed on map.
SizeLogarithmicAxis	The scale is used to map the values to symbol radius size, for logarithmic data. Provides the elements, as colored legend, which can provide the how the values are distributed on map.
TopoJson	TopoJSON is an extension of GeoJSON that encodes topology.
