I’ve never tried Dojo; thanks for pointing it out. Just now I looked at some demos and it seems to be useful. And sorry, I don’t know much about web applications for data visualization.

I know I am a bit late with the comment, but what do you think about Dojo?
Aren´t there any possibilities for data visualisation as well and beyond Google API?

What I meant by saying “poor” for GoogleVis API was: it has very limited capability of drawing genuine statistical graphics, e.g. histogram/density curve, boxplot, scatter plot with regression line or LOWESS curve, not to mention sunflower scatter plot, conditional density plot, contour plot/lines, mosaic plot, …

To the general audience, the bar/line/pie chart are much more common and easy to understand, but what they reveal is just the original data (or numbers) — little summary, no statistical inference and hence limited information.

For your question, I haven’t found a good API for (general) data visualization yet. There might be good ones for specific tasks, I think.

What is a good api for visualization?

I have included a demo function g.brownian.motion() in the R package ``animation'':

if(!require("animation")) install.packages("animation")
library(animation)
g.brownian.motion(15, digits = 2, width = 600, height = 500)
