Solution 1:

Adding transition() to enter/exit/remove calls will resolve your flicker problem.

var circleData = [50, 40, 30, 60, 70];

var svg = d3.select("body").append("svg")
  .attr("width", 500)
  .attr("height", 5000)

var circle = svg.append("circle")
  .attr("cx", 100)
  .attr("cy", 100)
  .attr("r", 25);

setTimeout(function() {
  updateCircles(circleData)
}, 2500)

function updateCircles(data) {

  var circles = svg.selectAll("circle")
    .data(circleData);

  circles.enter()
    .append("circle")
    .attr("cx", 100)
    .attr("cy", function(d, i) {
      return (i + 1) * 100
    })
    .attr("r", 0)
    .attr("fill", 'yellow')
    .transition()
    .duration(1500)
    .attr("r", function(d) {
      return d;
    });

  circles.transition()
    .duration(1500)
    .delay(1500)
    .style('fill', 'green')
    .attr('r', function(d) {
      return d;
    });

  circles.exit()
    .transition().duration(1500).delay(1500)
    .style("fill", "red")
    .transition().duration(1500).delay(3000)
    .attr("r", 0).transition().remove();
}
