Here instead of text, continuous circles should be coming, how we can achieve this?

Here is a simple Cubic Bezier (4 points) example:
const points = [{x: 0, y: 100}, {x: 100, y: 0}, {x: 200, y: 200}, {x: 300, y: 100}];
const cbPoint = t => {
const x = points[0].x * t * t * t +
points[1].x * 3 * t * t * (1 - t) +
points[2].x * 3 * t * (1 - t) * (1 - t) +
points[3].x * (1 - t) * (1 - t) * (1 - t);
const y = points[0].y * t * t * t +
points[1].y * 3 * t * t * (1 - t) +
points[2].y * 3 * t * (1 - t) * (1 - t) +
points[3].y * (1 - t) * (1 - t) * (1 - t);
return {x, y};
}
const RADIUS = 7;
const OFFSET = 25;
const WAVES = 2;
const svg = d3.select('svg');
const path = `M ${points[0].x},${points[0].y} C ${points[1].x},${points[1].y} ${points[2].x},${points[2].y} ${points[3].x},${points[3].y}`;
for (let index = 0; index < WAVES; index++) {
const g = svg.append('g');
g.attr('transform', `translate(${50 + index * 300}, 0)`);
g.append('path').attr('d', path).style('fill', 'none').style('stroke', 'black');
for (let t = 0; t < 1; t += 0.1) {
const {x, y} = cbPoint(t);
g.append('circle')
.attr('r', RADIUS)
.attr('cx', x)
.attr('cy', y + OFFSET)
}
