npm version

trelliscopejs-lib is a viewer for Trelliscope displays which can currently be created using the trelliscopejs R package (and hopefully in the future, conceptually created with anything else). This viewer is being written as a pure JavaScript application and the ultimate goal is for it to be able to plug in to many languages and be served by many back-ends depending on the scale of the display.

Trelliscope is a system for detailed interactive visualization of potentially very large data sets. The concept is to break a dataset into pieces, make a plot for each piece (each plot called a panel), and then arrange these plots into a grid or pages of grids for viewing. This idea is based on Trellis Display. When the number of panels becomes very large, Trelliscope provides a system for allowing the user to interactively explore the space of the panels based on metrics computed for each panel, called cognostics. To read more about Trelliscope, see here.
