`Agentmap.buildingify` accepts more arguments specifying the dimension and appearance of the units and streets it will build. For more on that, see the section on [Feature Styling](#feature-styling).

Navigating Streets
Given a neighborhood's streets in GeoJSON, AgentMaps extracts a street network and converts it to a graph with the help of the ngraph.graph library. Then, it uses ngraph.path to find an (approximately) shortest path. The graph itself is made out of the start point, end point, and intersections of each street.
The graph is stored in the Agentmap.streets.graph property. It is a symmetric graph; for each edge between two points, an inversely directed edge between them also exists. That is, by default, there are no one-way streets. However, if you'd like to remove some of the directed edges of certain streets from the graph (i.e. for making one-way streets), a very accessible guide to manipulating the graphs is available in the ngraph.graph README.
Navigating Within Units
Every Agentmap has an Agentmap.getUnitPoint method which makes it easy to specify a position inside of a unit, relative to one of its corners, and get back the global coordinates of that spot.
