The described technology is generally directed towards automated generation of network data visualization dashboards. Automation can be achieved through the use of templates and data files. Templates can be combined with any of multiple different data files to produce network data visualization dashboard files. Different combinations of templates and different data files can result in different network data visualization dashboard files. The network data visualization dashboard files can be provided to a data visualization tool, platform, or service, which can generate network data visualization dashboards according to received network data visualization files.
