Vizor

Vizor is a graph visualization and interactive exploration library developed by Aron Fiechter and Marco Raglianti @ REVEAL.

With Vizor you can:

• create graphs of objects
• map metrics to the nodes and edges representing such objects
• select entities manually or programmatically and spawn new subgraphs to refine your exploration
• choose how to layout entities on the canvas
• leverage predefined view specifications or create custom ones to visualize a subset of the nodes and edges
• ...

Vizor is developed in Pharo, tested with Pharo 8, and released under MIT License.

Installation and Usage

Load from Metacello

To add Vizor to a Pharo image you can run the following command in a playground.

Metacello new
    baseline: 'Vizor';
    repository: 'github://USIREVEAL:vizor';
    load.

Vizor as a library

If you wish to set a dependency to Vizor in your application, you simply need to add the following in your baseline:

| vizorVersion |
vizorVersion := 'main'.
spec
    baseline: 'Vizor'
    with: [
        spec repository: 'github://USIREVEAL:vizor:' , vizorVersion
    ]

Usage

See examples in Vizor-GUI - Examples.
