Q ATT Data Visualization
The question was based on an image, where two circle segments served as start and endpoint. Between these two, many lines were drawn in a smooth curved way.

Data can be taken in as ASCI code

This data is connected to an object’s vertices (points) and can be read out with XPresso. To see how that data has to be structured, use any object (editable) and export the data. In the example below, I used random data to distribute the start and the end while randomizing the “mid-area” via the Multiply node.
Create a three-point Spline, set to Cubic.
Copy it many times.
Connect and delete to get one.
(Perhaps do it again now, and so on, until the number fits your target)
The overall point (structure Manager) gives you the iteration. Starting with zero)
When the result is as you like to have it, disable the Xpresso
Hair is used, and the Color is set to Var: Hue.
All the best
