Answer 1

You can use the SVG as another HTML component, you can set its CSS properties:

For instance, on creating the svg, you set a class:

var svg = d3.select("body").append("svg")
    .attr("width", width + margin.right + margin.left)
    .attr("height", height + margin.top + margin.bottom)
    .attr("class", "graph-svg-component");

In your CSS you can define the property:

.graph-svg-component {
    background-color: AliceBlue;
}

Just add a <rect> as the first painting order item that displays the colour you want.

var svg = d3.select("body").append("svg")
    .attr("width", width + margin.right + margin.left)
    .attr("height", height + margin.top + margin.bottom);

svg.append("rect")
    .attr("width", "100%")
    .attr("height", "100%")
    .attr("fill", "pink");

svg.append("g")
    .attr("transform", "translate(" + margin.left + "," + margin.top + ")");
