I’m trying to port over an old visualization of a simple gravity simulation to observable, and rendering it with canvas rather than svg (so I can increase the complexity/number of particles)
To my surprise, the (stripped-down) observable+canvas version seems to be running slower - rendering about 10 times a second. When I try to monitor the performance (using Chrome’s dev tools) it says that the page is idle the vast majority of the time.
Am I misusing d3.interval (i also tried d3.timer with much the same result), inefficiently using observable or otherwise missing some obvious cause of syncopation?
