I have reached very near to fulfill my need. Just a little issue which I tried playing with calculations but stuck in. Snippet :
.path {
stroke-dasharray: 120;
stroke-dashoffset: -120;
animation: dash 3s linear infinite;
}
@keyframes dash {
to {
stroke-dashoffset: 0;
}

</svg>I just need small help to make the circle path animation start from the top. I am doing something wrong with the calculation I guess. I just need the animation like this. However it is using a third party js plugin which I don't want to use.
Also is there any way we can embed css into SVG so that we can have the graphic as .svg with animation instead to put svg code in html file?
If you need the stroke to start from the top of the circle, you need to change the path you used to make the circle. I made another one according to the formula described in this answer. I just modified it to make the path start on the top.
Then you can calculate the perimeter of the circle (π * 2 * r) for the stroke-dasharray and stroke-dashoffset values :
.path {
stroke-dasharray: 157;
stroke-dashoffset: -157;
animation: dash 6s linear infinite;
}
@keyframes dash {
to { stroke-dashoffset: 157; }
