BrowserViz-class.RdMany of the best interactive graphics capabilities available today are written in Javascript and run in a web browser. BrowserViz makes these capabilities available in R, using websockets for message passing back and forth between R and the browser. This class connects your R session to your web browser via websockets, using the R httupv library, which in turn uses the Rook webserver.
BrowserViz is a concrete base class, in that instances can be constructed and run - which we do for testing. The primary use of this BrowserViz is to be subclassed: to facilitate the creation of new browser-based, R-connected interactive graphics capabilities embodied in R packages, written by programmers with some skill in both R and Javascript. Two examples of this can be found in these Bioconductor packages https://bioconductor.org/packages/devel/bioc/html/igvR.html and https://bioconductor.org/packages/devel/bioc/html/RCyjs.html.
