IFrame Visualizations

Most visualizations require more than basic HTML. Embedding HTML directly in your console also risks conflicts between different parts of your code. The most flexible way to embed a web resource is using an IFrame:

R

library("cdsw")
iframe(src="https://www.youtube.com/embed/8pHzROP1D-w", width="854px", height="510px")

Python

from IPython.display import HTML
HTML('<iframe width="854" height="510" src="https://www.youtube.com/embed/8pHzROP1D-w"></iframe>')

You can generate HTML files within your console and display them in IFrames using the /cdn folder. The cdn folder persists and services static assets generated by your engine runs. For instance, you can embed a full HTML file with IFrames.

R

library("cdsw") 
f <- file("/cdn/index.html") 
html.content <- paste("<p>Here is a normal random variate:", rnorm(1), "</p>") 
writeLines(c(html.content), f) 
close(f) 
iframe("index.html")

Python

from IPython.display import HTML
import random

html_content  = "<p>Here is a normal random variate: %f </p>" % random.normalvariate(0,1)

file("/cdn/index.html", "w").write(html_content)
HTML("<iframe src=index.html>")
