Data visualization in one of three most important steps in data mining (https://github.com/entaroadun/hnpickup#readme). Often times, it's impossible to understand data without proper visualization. I went looking for great tools to do that.

Two website list recent JS visualization frameworks:

One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

	// Python equivalent:
	// string[start:end]
	function tt_str_slice($string, $start=NULL, $end=NULL) {
	$length = strlen($string);

	if ($start === NULL) {
	$start = 0;
	} else if ($start < 0) {
	$start = $length + $start;
	if ($start < 0) {
