Styling methods assign values that determine the rendered form and content of chart components, such as the text displayed, or the color and opacity of a given symbol. These methods belong to the d3-selection class but are addressed separately based on their specialized role in the chart-making process.

Modifying Elements

The methods collected here are used to apply values to a given selection, such as in the following code:

const path = svg.append("g")
.attr("fill", "none")
.attr("stroke", "steelblue")
.attr("stroke-width", 1.5)
.attr("stroke-linejoin", "round")
.attr("stroke-linecap", "round")

In this excerpt, a path is declared and followed by a series of chained .attr() calls that set the various properties that will be applied to the path such as the color ("steelblue"), and the width of the path (1.5).
