With the code below, the browser tab hangs, circling indefinitely.
The issue appears to be the rendering of two data-points that are very close apart

series1:
dataPoints: [
{ x: 3.001084, y: 235 },
]

series2:

dataPoints: [
{ x: 2.991214, y: 234 },
]

If I move the data points x of the series by 1 (increase or decrease), it works fine.. Looks like a bug?

try changing the 2.991214 to 2.591214 and the chart would load without an issue.
