This is the N4V FOR WEBI Wiki page for the OpenStreetMap map widget.

Since Need4Viz 2025.3.4

• OpenStreetMap map geolocates data (latitude / longitude) and can optionally display a tooltip.
  
• Defining an additional dimension and an associated measure also displays a chart (Pie, Pie3D, Donut, or Bar) around the pin.
  
• Users may add annotations on the map (calculation of distances, areas, drawings …) if drawing tools are enabled.

• Dimension 1 : Latitude
• Dimension 2 : Longitude
• Dimension 3 : Tooltip
• Dimension 4 : Dimension for the pie chart

• Measure 1 : Main measure for the pie chart
• Measure 2 : [Optional] Second measure for pin color
