This repository has the ability to create SVG tree maps with Javascript, without any frameworks!
tree(element, [
{"key": "test1", "text": "test 1", targets: ["test3", "test5"]},
{"key": "test2", "text": "test 2", targets: ["test3"]},
{"key": "test3", "text": "test 3"},
{"key": "test4", "text": "test 4"},
{"key": "test5", "text": "test 5"}
], {});
