Looking for ways to improve performance with large data sets with a line chart. Need to have 50,000 ~ 200,000 possibly more data points and once it goes over 20,000 the performance drops off significantly.
For each data point it creates an element like this : <circle class="dot" r="1.25" fill="#1f77b4" style="fill-opacity: 1e-06; stroke-opacity: 1e-06;" cy="152" cx="2.7857966438401953"></circle>
Anyone know of a way to achieve the same effect with better performance, If I could get a reference to the nearest data point with a mouseover/mousemove event handler that would probably work.
Thanks
