You can accomplish this with a properly specified radial gradient - for example

I have modified your code and made changes for roundedCornersFor. It will now take an object structure which will define take start and end as keys and the values will be the arc positions which are according to labels.

It's because of the default spacing assumed between two consecutive values, which is 1. See this answer for details.

In your examples, spacing can be found as

If I have time tomorrow I will try to implement the following to your code but I can provide you with a working example of how to get mouse collision precision on a rotated rectangle. I had the same struggle with this and finally found a good explanation and code that I was able to get to work. Check out this website

Now for my own implementation I did not use the method on that website to get my vertices. As you'll see in my code I have a function called updateCorners() in my Square class. I also have objects called this.tl.x and this.tl.y (for each corner).

The formulas are what I use to get vertices of a translated and rotated rectangle and the corner objects are what are used to determine collision. From there I used the distance() function (Pythagorean theorem), the triangleArea() function, and then the clickHit() function which I renamed to collision() and changed some things.

Example in the snippet below

This is what I achieved:

I'm not entirely sure if you wanted x to range from [-pi,pi] or [0,2pi]. If you want the range [0,2pi] instead, just comment out the lines ax.set_xlim and ax.set_xticks.

Use separate try statements for each input with their own loops

The problem is - the code is rendering the complete path - start-to-end each time and start is same for all animations.

The idea for loaders is - start point has to change after each animation - something like -

1. Start at angle 0
2. Go up to angle 45 /// or 60 whatever you want this to be
3. Change start angle to next logical step - say 30
4. Then render up to 75 /// or 90 depending on what you chose previously

In this arrangement, you have to keep drawing a certain portion of the shape by changing start point continuously.

In practice, achieving a smooth transition between different start point values may prove out to be difficult than it seems. You can find an example here - https://github.com/SVProgressHUD/SVProgressHUD/blob/master/SVProgressHUD/SVIndefiniteAnimatedView.m#L48-L102

UPDATE

The link I shared above has all the hints in it. This library uses an image as a mask and then rotate that continuously. Mask shape can be anything you like - you already have code for that.

You just need to create an image that's appropriate for your animation. See what their asset looks like

and AFTER masking what their animation looks like -

You need to wrap all your content except img in separate div and you need to add flex to your ".burger-item " , and you need to change some styles for your ".burgerimg "

But i suggest you change something , and experiment on your own

Working code :

Thanks to the comment from TrentonMcKinney I realized what the issue was:

In my case:

The values in each of my rows are the same, but each row is increasing.

But what I need for streamplot to work is:

Each row is the same, but the values in each row are increasing.

So I changed indexing = 'ij' to = 'xy':
