This is making me feel exceptionally stupid, but I was messing around with D3js(v4) today, and I am seeing some unexpected behavior regarding the behavior of method chaining. For this example [LINK] everything works as expected -- great! Below is an example of the code that works: function render (data) { const circles = svg.selectAll('circle').data(data); circles.enter().append('circle').attr("r", circleRadius) .attr("class", "vote") .attr("cx", function (d) { return d.x}) .attr("cy", function (d) { return d.y}); circles.exit().remove(); } However, in this example [LINK] , I ended the circle chain to start a new one, and everything breaks. Below is an example of the problematic code: functi
