SVG element's don't have title attributes; https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute

See http://bl.ocks.org/ilyabo/1339996 for an example of adding the title element.

For your code, use:

sel
.selectAll("svg")
...
.on("click", (_, d) => choose(d))
.append("svg:title").text( d => d.name);
