D3.js chain transitions for compound animations for different shapes

Question

What I\'m trying to do...

I\'m toying with D3 to make a compound animation. I have the following final state:

Answer 1

The transition are easier to chain since d3.v3 without using "end". See the notes here.

For example, look at this one:

rect.transition()
  .duration(500)
  .delay(function(d, i) { return i * 10; })
  .attr("x", function(d, i, j) { return x(d.x) + x.rangeBand() / n * j; })
  .attr("width", x.rangeBand() / n)
  .transition()
  .attr("y", function(d) { return y(d.y); })
  .attr("height", function(d) { return height - y(d.y); });

That's for transitions on the same element. For different elements, look at this one.

// First transition the line & label to the new city.
var t0 = svg.transition().duration(750);
t0.selectAll(".line").attr("d", line);
t0.selectAll(".label").attr("transform", transform).text(city);

// Then transition the y-axis.
y.domain(d3.extent(data, function(d) { return d[city]; }));
var t1 = t0.transition();
t1.selectAll(".line").attr("d", line);
t1.selectAll(".label").attr("transform", transform);
t1.selectAll(".y.axis").call(yAxis);

The transition is attached to the svg element and chained from there.
