Package Exports
- flowchart.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (flowchart.js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Example
Requirements
You will need Raphaël
CDN
flowchart.js is on CDNJS, feel free to use it
Usage
On your page you need to include Raphaël like so:
<script src="raphael-min.js"></script>
or
npm install flowchart.js
and 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:$myFunction\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' }
}
});
// function called when you click the "My Operation" node
function myFunction(event, node) {
console.log("You just clicked this node:", node);
}
</script>
Node Syntax
nodeName=>nodeType: nodeText[|flowstate][:>urlLink]
nodeName defines the nodes variable name within the flowchart document.
nodeType defines what type the node is. See Node Types for more information.
nodeText is the text that will be inserted into the node. Newlines are allowed and will be reflected in the rendered node text.
flowstate is optional and uses the |
operator that specifies extra styling for the node.
urlLink is optional and uses the :>
operator to specify the url to link to.
Node Types
Defines the shape that the node will take.
start
Used as the first node where flows start from.
st=>start: start
end
Used as the last node where a flow ends.
e=>end: end
operation
Indicates that an operation needs to happen in the flow.
op1=>operation: operation
inputoutput
Indicates that IO happens in a flow.
io=>inputoutput: inputoutput
subroutine
Indicates that a subroutine happens in the flow and that there should be another flowchart that documents this subroutine.
sub1=>subroutine: subroutine
condition
Allows for a conditional or logical statement to direct the flow into one of two or more paths.
cond=>condition: condition
Yes or No?
parallel
Allows for multiple flows to happen simultaneously.
para=>parallel: parallel
Links
A external link can be added to a node with the :>
operator.
The st
node is linked to http://www.google.com
and will open a new tab because [blank]
is at the end of the URL.
The e
node is linked to http://www.yahoo.com
and will cause the page to navigate to that page instead of opening a new tab.
st=>start: Start:>http://www.google.com[blank]
e=>end: End:>http://www.yahoo.com
Advice
Symbols that should possibly not be used in the text: =>
and ->
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"})

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