Network visualization
With the integration of D3.js data can be visualized as a network graph available at the Network visualization button at the Overview or as an egocentric network at the entity detail view.
Classic is the default but it can be switched to other types at the top of the visualization pages.
Options
Colors - you can change the node color of classes
Depth - in egocentric networks you can define the link depth
Show orphans - if nodes without connections should be shown too
Width - the width of the resulting image in pixel
Height - the height of the resulting image in pixel
Charge - a parameter for the distance between entries which are not connected
Distance - a parameter for the distance between connected entries
In case of performance issues
Check if your browser has hardware acceleration enabled
Try different browsers, some are faster than others when dealing with large data sets
Download
If an image is available (classic mode only) you can download it as PNG. Be aware that the resulting image is exactly what you see in this moment so you may want to change width and height in the options before. Also you may want to choose a zoom level where labels are readable.
