'Draw an arc between two points with radius in javascript canvas
I need to draw an arc with R radius between two points x1,y1 and x2,y2. I'm trying to draw this arc on html canvas. I'll add two examples along with this question.

You can render arc like:
ctx.beginPath();
ctx.arc(100, 100, 50, 0, Math.PI, true);
ctx.stroke();
Params 100/100 - arc center, 50 - radius.
If you want to render between 2 dots - you need to find center dot(like centerX = x1 + (x2 - x1) / 2).
More you can read here and find some examples:
