I looked into a lot of charting libraries, but none of them met my needs. For example, that library doesn't look like it supports complex background coloring, or panning/zooming the chart.
As for performace, ignoring the initial load time, this was by far the fastest solution I came across. Most libraries I tested slowed down on hundreds of points, but plotly worked fine.
