Choose a region on a scatter plot using JavaScript

My current challenge involves utilizing JavaScript to achieve the following tasks:

  1. Create a scatter plot consisting of approximately 10,000 data points
  2. Enable users to draw a curved shape on top of the plot in order to select a specific region (The design of the shape can vary from an ellipse to a polygon, or even a bezier curve-defined path)
  3. Retrieve a list of points within the selected area and perform actions with them.

The primary obstacle lies in step 2. I have previously utilized jqplot for a similar task involving rectangular selection, but it is crucial for this project that users are able to select an elliptical region instead.

I would greatly appreciate any suggestions regarding which JavaScript library would be suitable for implementing this functionality.
