Network Visuals

Network visuals may be used to represent many systems and structures. Our implementation is dynamic, with ongoing optimization adjustment. It also includes many manual setting adjustments.

We are working with dataset NYC Taxi Data for year 2013.

You can download a subset of this data for trips made within Staten Island boro, upload it, and create the dataset NYC Taxi Data. For an overview of shelves that specify this visual, see Shelves for Network Visuals.
