An arc diagram is a style of graph drawing, in which the vertices of a graph are placed along a line in the Euclidean plane, with edges being drawn as semicircles in one or both of the two halfplanes bounded by the line, or as smooth curves formed by sequences of semicircles. In some cases, line segments of the line itself are also allowed as ...
In addition to spatial data editing and visualization, ArcGIS provides spatial analysis and modeling features including overlay, surface, proximity, suitability, and network analysis, as well as interpolation analysis and other geostatistical modeling techniques. Python, Web API, .NET: Proprietary. Analytical extensions can be purchased separately.
Python is, or can be used as the scripting language in these notable software products: Abaqus (Finite Element Software) ADvantage Framework; Amarok; ArcGIS, a prominent GIS platform, allows extensive modelling using Python; Autodesk Maya, professional 3D modeler allows Python scripting as an alternative to MEL as of version 8.5; Autodesk ...
Plugins are provided for Autocad (for designers), ArcGIS, open source QGIS (for analysts & designers) and as a standalone Python version that works on 2D or 3D shapefiles enabling use in other GIS software and custom projects. sDNA standardizes on the network link as a unit of analysis, and computes a wide variety of closeness, betweenness ...
ArcGIS Pro also supports streamlined workflows that involve publishing and consuming feature layers using ArcGIS Online. [57] With the release of ArcGIS Pro 3.0 in June, 2022 all *.aprx project files can be read by version 3.0; however, if the project is saved it will render the project file to be incompatible with version 2.9.x and earlier.

NetworkX is suitable for operation on large real-world graphs: e.g., graphs in excess of 10 million nodes and 100 million edges. [ clarification needed ] [ 19 ] Due to its dependence on a pure-Python "dictionary of dictionary" data structure, NetworkX is a reasonably efficient, very scalable , highly portable framework for network and social ...
A directed graph is weakly connected (or just connected [9]) if the undirected underlying graph obtained by replacing all directed edges of the graph with undirected edges is a connected graph. A directed graph is strongly connected or strong if it contains a directed path from x to y (and from y to x) for every pair of vertices (x, y).
A circular-arc graph (left) and a corresponding arc model (right). In graph theory, a circular-arc graph is the intersection graph of a set of arcs on the circle. It has one vertex for each arc in the set, and an edge between every pair of vertices corresponding to arcs that intersect.
