I'm trying to upgrade the following donut chart from d3.js v3 to d3.js v4.

I have replaced all the old version method names with the equivalant methods in new version.

d3.scale.ordinal() to d3.scaleOrdinal()

d3.layout.pie() to d3.pie()

d3.svg.arc() to d3.arc()

The "d" attribute of path tag not getting generated.

And the methods "attrTween and styleTween" not even getting triggered in v4.

I have created a plunker for this.

Reset to default 8

The enter, update, and exit pattern changed slightly in d3.js v4. You now need to incorporate the .merge statement.

var slice = svg.select(".slices").selectAll("path.slice")
    .data(pie(data), key);

slice.enter()
    .insert("path")
    .style("fill", function(d) { return color(d.data.label); })
    .attr("class", "slice") //<-- enter selection
    .merge(slice) //<-- merge back in update selection
    .transition().duration(1000)
    .attrTween("d", function(d) {
        this._current = this._current || d;
        var interpolate = d3.interpolate(this._current, d);
        this._current = interpolate(0);
        return function(t) {
            return arc(interpolate(t));
        };
    });

Updated plunker.
