[[File:Network_chart_menu_Main.png|left|thumb|400px450px|Fig. {{#var:chapter}}.{{#vardefineecho:figure|{{#expr:{{#var:figure}}+1}}}} Network Chart {{man label|Main}} preferences tab]]

The filename {{man label|Filename:}} defaults to the database 'family tree name ' + '_network' with '.svg'(default) added automatically on output. The {{man label|Enter Chart Title :}} field defaults to the database family tree name and the folder {{man label|Folder:}} to the users top level user default homefolder. Once an entry is changed it will be remembered and used for the next time as well. Clearing the entry will set it back to default. Additionally, name and date formats for the chart can be modified using the Gramps available formatting. The output File Type can be changed to a PDF. The PDF will not have URL links but everything else will display the same as the SVG.

;{{man label|Enter Font Name:}} selection is straightforward, obtain the name of the font that you wish to use and type it in the entry box.: The only requirement is that the font already be installed on your system. If the font is not found then a default font will be used. This is a silent operation and will not warn on a font not found. When the SVG graph is generated that font will be identified for use, however, if someone viewing the chart does not have the same font installed they will see their default font instead. (Embedding fonts in SVGs or making them a local access is possible but not available in this addon.) The default font is White Rabbit by Matthew Welch which is an extremely readable font. It can be obtained from https://www.fontsquirrel.com/fonts/white-rabbit and the license found at http://www.squaregear.net/fonts/license.shtml .

Finally, you can use "the {{man label|[ ] Different node shape/edges for gender" }} checkbox to controls control the box shapes and makes make the Male and Female box shapes different, by default this selection is turned off.

Network Chart requires the python Python networkx module to assist in selecting what to display and Graphviz via the pygraphviz module to generate the chart.

You can check if networkx and pygraphviz installed correctly by starting python Python (type python3 if system default is still python 2) and attempt to import both packages[https://www.reddit.com/r/gramps/comments/5z1gtj/show_all_database_entries_in_a_graphical_report/deuym8w/] eg:

Network Chart was intended created for smaller small databases or subsets and is extremely fast for charts with less than 1500 nodes. However, it can generate very large graphs in reasonable time and should be adequate for those large databases that do not change frequently. Some optimizations for large databases are done automatically. The Trim Groups selection is one. Another method to greatly decrease the time to generate a chart on a large database is to select Straight or Curved for the Graph Style on the {{man label|[[Addon:NetworkChart#Main|Main]]}} preferences tab. Reducing the number of nodes to graph via {{man label|[[Addon:NetworkChart#Trim|Trim]]}} and {{man label|[[Addon:NetworkChart#Highlight|Highlight]]}} tabs will reduce graph generation times. For example, if your database contains 65535 individuals and you trim or highlight to plot only 8191 individuals, it would take closer to 20 seconds to generate the chart (based on the following table).
