How to set the background-color of a D3.js svg?

I'm not very familiar in styling D3.js SVG's. I create a collapsible tree and will provide an option to download this tree as SVG/PDF/PNG. This works great but the background-color of the resulting files is always transparent. Is there a possibility to create the D3 SVG with a specific background-color? I used this example for my work:

Thank you!

Use .style() to control the CSS properties:

const svg = d3.create("svg")
              .attr("viewBox", [-width/2, -15, width/1.3, height])
              .attr("width", width)
              .attr("height", height)
              .attr("style", "max-width: 100%; height: auto; height: intrinsic;")
              .attr("font-family", "sans-serif")
              .attr("font-size", 15)
              .style("background", "yellow");

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 + ")");
