We have added the generation of legends for v1.1. Legend are a mandatory component to any visualizations because they help communicate the meaning of nodes, edges, colors, sizes and icons. However they usually take a lot of time to craft. In Linkurious, legends are automatically generated based on the mapping between data properties and visual variables set in the Design panel of the Workspace.
Users can display legends when publishing interactive widgets. They can also downloaded them in PNG file or SVG file separatedly from the Workspace > Export menu. PNG files can be added easily is presentations and reports, while SVG files are best for print on any size and can be edited in software such as Inkscape or Adobe Illustrator.
The following image is an example of a typical legend from our demo, where the database is a subset of Crunchbase. Node colors and size are mapped to a property called “funding total”. Node icons represent categories of nodes. Edge color is mapped to a property called “funded year”, and edge size corresponds to the “raised amound in USD”.
