To set the stroke width in d3.js, you can use the style method to apply CSS styles to the elements you want to modify. Here is an example of setting the stroke width for a line in d3.js:

2

d3.select("line")
    .style("stroke-width", "2px");

In this example, we are selecting a line element in the DOM and setting its stroke width to 2 pixels. You can adjust the value inside the style method to change the stroke width as needed.
