A WebUI control for visualizing and editing flow charts.
This isn't designed to be completely general purpose, but it will be a good basis if you need an SVG flowchart and you are willing to work with AngularJS.

Include the following Javascript in your HTML file:
<script src="flowchart/svg_class.js" type="text/javascript"></script>
<script src="flowchart/mouse_capture_service.js" type="text/javascript"></script>
<script src="flowchart/dragging_service.js" type="text/javascript"></script>
<script src="flowchart/flowchart_viewmodel.js" type="text/javascript"></script>
<script src="flowchart/flowchart_directive.js" type="text/javascript"></script>Make a dependency on the the flowchart's AngularJS module from your application (or other module):
angular.module('app', ['flowChart', ])In your application (or other) controller setup a data-model for the initial flowchart (or AJAX the data-model in from a JSON resource):
var chartDataModel = {
nodes: [
{
name: "Example Node 1",
id: 0,
x: 0,
y: 0,
inputConnectors: [
{
name: "A",
},
{
name: "B",
},
{
name: "C",
},
],
outputConnectors: [
{
name: "A",
},
{
name: "B",
},
{
name: "C",
},
],
},
{
name: "Example Node 2",
id: 1,
x: 400,
y: 200,
inputConnectors: [
{
name: "A",
},
{
name: "B",
},
{
name: "C",
},
],
outputConnectors: [
{
name: "A",
},
{
name: "B",
},
{
name: "C",
},
],
},
],
connections: [
{
source: {
nodeID: 0,
connectorIndex: 1,
},
dest: {
nodeID: 1,
connectorIndex: 2,
},
},
]
};Also in your controller, wrap the data-model in a view-model and add it to the AngularJS scope:
$scope.chartViewModel = new flowchart.ChartViewModel(chartDataModel);Your code is in direct control of creation of the view-model, so you can interact with it in almost anyway you want.
Finally instantiate the flowchart's AngularJS directive in your HTML:
<flow-chart
style="margin: 5px; width: 100%; height: 100%;"
chart="chartViewModel"
>
</flow-chart>Be sure to bind your view-model as the 'chart' attribute!
