how to make hyperlink <a href > from node

Good day. Trying to make in SVG something hyperlink like this:

in VivaGraphJS code i try:

graphics.node(function(node) {
var ui = Viva.Graph.svg("g"),

svgText = Viva.Graph.svg("text").attr("y", "-4px").text(node.id),

img = Viva.Graph.svg("image")
.attr("width", nodeSize)
.attr("height", nodeSize)
.link("https://secure.gravatar.com/avatar/" + node.data),

a = Viva.Graph.svg("a").attr("href", "https://vitalii-u.com/");
// .text('some text')
ui.append(svgText);
ui.append(a);
ui.append(img);
return ui;
})

and in browser i see:

function text(textContent) {
if (textContent !== undefined) {
svgElement.textContent = textContent;
return svgElement;
}
return svgElement.textContent;
}

I don't understand, what need to wrap image or text or thomething be giperlink ?
Thank you.

Start from the graphics.node callback shown in the issue and inspect how Viva.Graph.svg("a") handles appended elements and the displayed text function. Reproduce the generated SVG in a browser, then verify that the intended image or text is wrapped as a hyperlink and no function source appears in the output.
