You will need Raphaël
flowchart.js is on CDNJS, feel free to use it
On your page you need to include raphael like so:
<script src="raphael-min.js"></script>or
npm install flowchart.jsand then
<div id="diagram">Diagram will be placed here</div>
<script src="flowchart.js"></script>
<script>
var diagram = flowchart.parse('st=>start: Start:>http://www.google.com[blank]\n' +
'e=>end:>http://www.google.com\n' +
'op1=>operation: My Operation\n' +
'op2=>operation: Stuff|current\n' +
'sub1=>subroutine: My Subroutine\n' +
'cond=>condition: Yes \n' + // use cond(align-next=no) to disable vertical align of symbols below
'or No?\n:>http://www.google.com\n' +
'c2=>condition: Good idea|rejected\n' +
'io=>inputoutput: catch something...|request\n' +
'\n' +
'st->op1(right)->cond\n' +
'cond(yes, right)->c2\n' + // conditions can also be redirected like cond(yes, bottom) or cond(yes, right)
'cond(no)->sub1(left)->op1\n' + // the other symbols too...
'c2(true)->io->e\n' +
'c2(false)->op2->e' //allow for true and false in conditionals
);
diagram.drawSVG('diagram');
// you can also try to pass options:
diagram.drawSVG('diagram', {
'x': 0,
'y': 0,
'line-width': 3,
'line-length': 50,
'text-margin': 10,
'font-size': 14,
'font-color': 'black',
'line-color': 'black',
'element-color': 'black',
'fill': 'white',
'yes-text': 'yes',
'no-text': 'no',
'arrow-end': 'block',
'scale': 1,
// style symbol types
'symbols': {
'start': {
'font-color': 'red',
'element-color': 'green',
'fill': 'yellow'
},
'end':{
'class': 'end-element'
}
},
// even flowstate support ;-)
'flowstate' : {
// 'past' : { 'fill' : '#CCCCCC', 'font-size' : 12},
// 'current' : {'fill' : 'yellow', 'font-color' : 'red', 'font-weight' : 'bold'},
// 'future' : { 'fill' : '#FFFF99'},
'request' : { 'fill' : 'blue'}//,
// 'invalid': {'fill' : '#444444'},
// 'approved' : { 'fill' : '#58C4A3', 'font-size' : 12, 'yes-text' : 'APPROVED', 'no-text' : 'n/a' },
// 'rejected' : { 'fill' : '#C45879', 'font-size' : 12, 'yes-text' : 'n/a', 'no-text' : 'REJECTED' }
}
});
</script>Symbols that should possibly not be used in the text: '=>' and '->' and ':>' and '|' and '@>'
If you want to emphasize a specific path in your flowchart, you can additionally define it like this:
st@>op1({"stroke":"Red"})@>cond({"stroke":"Red","stroke-width":6,"arrow-end":"classic-wide-long"})@>c2({"stroke":"Red"})@>op2({"stroke":"Red"})@>e({"stroke":"Red"})

Many thanks to js-sequence-diagrams which greatly inspired this project, and forms the basis for the syntax.
