The text element, as its name describes, is used to display text in SVG. The basic HTML code to create a text node is as follows:

<text x="250" y="150">Hello world!</text>

It has an x and a y coordinate to tell it where to begin writing in the SVG coordinate system. Styling can be achieved with a CSS class in order to have a clear separation of concerns within our code base. For example, check out the following code:

<text x="250" y="150" class="myText">Hello world!</text>

.myText{
  font-size:22px;
  font-family:Helvetica;
  stroke-width:2;
}

Text also supports rotation in order to provide flexibility when positioning it on the visualization:

<svg width="600" height="600">
        <text x="250" y="150" class="myText" transform="rotate(45,200,0)" font-family="Verdana" font-size="100">Hello world!</text>
</svg>
