d3.voronoi mutates data about d3-voronoi HOT 3 CLOSED

d3.voronoi does not mutate the input data. Internally, it wraps each element in the input data array in a new object called a site (a two-element array [x, y]). The site also stores a reference to the original data element as the data property.

Some of the voronoi methods expose the site objects. Others return the original elements from the input data array, such as voronoi.triangles.

For some reason, I was seeing these site arrays, and the data object when I logged my original data. Also was experiencing this:

    var cells = dataLr.selectAll(".data-bub").data(d3.voronoi()
            .extent([
                [-100, -100],
                [svgWidth, svgHeight]
            ])
            .x(function(d) {
                //console.log(d);
                return d.x;
            })
            .y(function(d) {
                return d.y;
            })
            .polygons(fData),
            function(d) {
                console.log(d); //my properties are logged
                console(d.data.id); //the property itself returns undefined
            })
        .enter().append("g");

But now I'm not seeing that, and I have decided not to try to key the diagram. Thank you for explainig.

Overall, trying to learn what d3 modules do to my data by logging it to the console seems to be a very bad idea as the console is logging the end state no matter where in the code the command is.
