Lyra is an interactive environment that enables custom visualization design without writing any code. Graphical “marks” can be bound to data fields using property drop zones; dynamically positioned using connectors; and directly moved, rotated, and resized using handles. Lyra also provides a data pipeline interface for iterative visual specification of data transformations and layout algorithms. Lyra is more expressive than interactive systems like Tableau, allowing designers to create custom visualizations comparable to hand-coded visualizations built with D3 or Processing. These visualizations can then be easily published and reused on the Web.
To work on Lyra locally, you must have Node installed on your computer. Download this repository with Git, then (from the command prompt or terminal) check out the
lyra2 development branch with the command
git checkout lyra2
Once you are on the lyra2 branch, run
to install the project's code dependencies.
To build the application itself, execute the build command:
npm run build
Lyra is now ready to run. Start the local webserver with the command:
npm run build should only be necessary if you update the SCSS stylesheets.
