Map the output of dodgr_flows_aggregate or dodgr_flows_disperse

dodgr_flowmap(net, bbox = NULL, linescale = 1)

net | A street network with a |
---|---|

bbox | If given, scale the map to this bbox, otherwise use entire extend
of |

linescale | Maximal thickness of plotted lines |

`net`

should be first passed through `merge_directed_flows`

prior to plotting, otherwise lines for different directions will be overlaid.
