Introduction

TouchGraph is the producer of data visualization software TouchGraph Navigator 2. With TouchGraph Navigator 2, users can upload data and create "interactive network visualizations."[1] Users can purchase licenses for either a TouchGraph Navigator Desktop version or TouchGraph Navigator Web, where the user hosts visualizations on their server and views the visualization on a web browser.[1]

Use

Users first load the data (in Excel, Csv, Tsv, Multi Csv, MySql, Nav DB API, Vna, Gdf, or Pajek formats), and they then can define:[2]

  • Data types and delimiters - Data type (integers, text, url, etc) and delimiters of table fields.
  • Entities and relations - Specify how table data is transformed into Entity types and Relation types.
  • Dynamic relations - Direct connections between entities which were only indirectly connected in the data.
  • Dynamic attributes - Attribute that is derived from loaded data rather the being read directly from the file.
  • Aliases - Renaming entities, relations, and attributes.

Users then define the settings:[3]

  • Names: Types/Attributes, Entity Labels
  • Filter: Inclusion (which node types and edge types will be displayed in the graph), Attribute Filters (threshold values which determine which nodes and edges are displayed in the graph)
  • Node Appearance: Colors, Halo Size/Shape, Label/Image, Node Tags
  • Edge Appearance: Colors, Width/Pattern, Tags/Arrows
  • Graph Layout

On the graph panel, users view the network visualization, filter the "Connected Components/Degrees of Separation" (filtering the graph to show a specified number of degrees of separation around selected nodes), and zoom or alter spacing in the graph.[4]
