HTML Visualizations

Your code can generate and display HTML in Cloudera Data Science Workbench.

To create an HTML widget, paste in the following:

R

library("cdsw") 
html('<svg><circle cx="50" cy="50" r="50" fill="red" /></svg>')

Python 2

from IPython.display import HTML
HTML('<svg><circle cx="50" cy="50" r="50" fill="red" /></svg>')

Scala

Cloudera Machine Learning allows you to build visualization libraries for Scala using jvm-repr. The following example demonstrates how to register a custom HTML representation with the "text/html" mimetype in Cloudera Data Science Workbench. This output will render as HTML in your workbench session.

//HTML representation
case class HTML(html: String)

//Register a displayer to render html 
Displayers.register(classOf[HTML],
  new Displayer[HTML] {
    override def display(html: HTML): java.util.Map[String, String] = {
      Map(
        "text/html" -> html.html
      ).asJava
    }
  })

val helloHTML = HTML("<h1> <em> Hello World </em> </h1>")
  
display(helloHTML)
