Map Points Chart Options
This page describes the options for editing map points charts in the visualization menu. This menu can be accessed by clicking the gear in the upper right corner of the visualization tab.
Map Points charts are useful for plotting data represented by points on a map. To plot regions, use Map Regions. Map Point charts plot a single dimension of type: location, and a single measure. Additional dimensions will be shown in the tool-tip on hover.
Please note that your data must be grouped appropriately for the visualization type (regions map or points map) and specific map (US, UK, World, etc.) that you choose. See the Map section below for guidance. Some of the options listed below may be grayed out or hidden in situations where they would conflict with other settings you have chosen.

- Custom: Enables you to define your own map using TopoJSON
TopoJSON URL
For map charts set to Map Custom, TopoJSON URL sets the location of a TopoJSON file that defines your map boundaries.
TopoJSON Object Key
For map charts set to Map Custom, TopoJSON Object Key selects which map from the TopoJSON file to plot, since TopoJSON can support multiple maps in a single file. Set this parameter to one of the map names defined in the file.
Projection
For map charts set to Map Custom, Projection enables you to choose which D3 projection will be used to render your map. Examples of the many options are shown here.
