Aw: GWT Visualization Performance/Optimization

We were using 5 scatter charts each of them displaying around 2000 points and it worked pretty well and it didn't really take long to render it (maybe a sec oder so).

The Google Visualization scatter charts use SVG which doesn't scale that well with increasing number of objects. 

If performance is really important you can try to use a scatterplot which is based on canvas. 

We successfully switched from the google visualization scatter charts to dygraph (http://dygraphs.com/). Dygraph is based on cavnas and performs really good and hase also zooming and other useful features. 

They even support Google Visualization DataTable as datasource.
