PONY Tree is an open-source JavaScript library for vizualisation of Phylogenetic tree.

How it works?

You need to add the ponytree javascript script

<script src="ponytree.js"></script>

and to have a svg with a specific id (here the id is my_svg)

<svg id="my_svg" viewBox="0 0 1000 800" preserveAspectRatio="xMidYMin slice">

and a string represented a phylogenic tree in newick format for example (here it corresponds to the value of the textarea of id input_newick).

<textarea class="form-control" id="input_newick">

Now, you must initialize a variable pony with initiate_pony, compute a tree l with pony.tree, add some options with pony.option and build the tree l with the options of pony in the svg of id my_svg with pony.build.

var pony = initiate_pony();
var newick_text = document.getElementById(input_newick).value;
var l = pony.tree(newick_text,"Newick_Beast");
pony.option["use_scale"] = false;

And we obtain this tree.
