Scalability of threadlet

[phongvis]

What is the maximum number of threads that is suitable for our tool?

• Showing 1000 threads in a small scatter plot 200 x 100 is not ideal
• Technically, the visualisation can't handle a few thousands SVG elements. Interaction is really slow. Even with 100 threads, rugs added, there are 1300 SVG elements, and the interaction is noticeable slow.

leave as it is; test with 100 threads, can try 300, 500 to check scalability
