Connect Points on a Map with Dynamic Lines

Connect points on a map using a dynamic line map layer type to quickly visualize the connections.

Use defined origin attribute columns as start nodes and defined destination attribute columns as end nodes to create the dynamic lines.

For example, to generate dynamic lines between a source airport and all of its destination airports, you might use attribute columns called Source Airport Latitude and Source Airport Longitude as the start nodes and destination attribute columns called Target Airport Latitude and Target Airport Longitude as the end nodes.
