InteractiveGraph provides a web-based interactive operating framwork for large graph data, which may come from a GSON file, or an online Neo4j graph database.
InteractiveGraph also provides three applications built on the framework: `GraphNavigator`, `GraphExplorer` and `RelFinder`.
__GraphNavigator__: online demo https://grapheco.github.io/InteractiveGraph/dist/examples/example1.html
__GraphExplorer__: online demo
https://grapheco.github.io/InteractiveGraph/dist/examples/example2.html
__RelFinder__: online demo https://grapheco.github.io/InteractiveGraph/dist/examples/example3.html
## Quick start
__Step 1.__ download `examples.zip`:
https://github.com/grapheco/InteractiveGraph/releases
__Step 2.__ unzip and deploy `examples.zip` as a webapp in a Web server (Apache, Tomcat, etc). A Web server is required, otherwise the graph data loading via AJAX will get an error.
__Step 3.__ visit the webapp in Web browser, url may looks like:
https://localhost:8080/examples/example1.html
change `example1.html` to `examples2.html` or `examples3.html`, etc.
## How to use
__Step 1.__ download `interactive-graph-.zip`(`interactive-graph-0.1.0.zip`, for example) from `dist` directory:
https://github.com/grapheco/InteractiveGraph/dist/
__Step 2.__ unzip `interactive-graph-.zip`, two files will be got: `interactive-graph.min.js` and `interactive-graph.min.css`.
__Step 3.__ import the `.js` and `.css` files in HTML page, like that:
```javascript
```
__Step 4.__ use functions and classes defined in `igraph` namespace:
```javascript
igraph.i18n.setLanguage("chs");
var app = new igraph.GraphNavigator(document.getElementById('graphArea'));
app.loadGson("honglou.json");
```
As shown above, a `GraphNavigator` application object is created and used to load graph data from `honglou.json`.
For more details, see https://github.com/grapheco/InteractiveGraph/blob/master/dist/examples/example1.html.
To develop custom applications, it is a good idea to write new application classes derived on `GraphNavigator` and other application classes. Furthermore, users can create new application classes via using a `MainFrame` class directly.
### InteractiveGraph API
InteractiveGraph is written in TypeScript. Visit https://grapheco.github.io/InteractiveGraph/dist/api/index.html to get online API documents.
### dependencies
This project depends on some open sourced components including `visjs`, `npm`, `gulp`, `jQuery`, `jQueryUI`, `Font Awesome` and so on.
More dependencies, see https://github.com/grapheco/InteractiveGraph/blob/master/package.json.
InteractiveGraph provides a MainFrame, which actually is a facade of Web UI, event handling and graph data connection.
As shown above, MainFrame consists of a main graph rendering canvas, a set of navigation buttons, and serveral controls: search bar, tool bar, info box, highlight control and so on.
Some controls have Web UI, such as InfoBoxCtrl, MessageBoxCtrl, etc. While others work with no UI, such as HighlightNodeCtrl, ExpansionCtrl, etc. A `Control` class and two derived classes `UIControl`(controls with UI) and `BGControl`(backgroud control with no UI) are defined in InteractiveGraph.
All controls are listed in the table below.
| control | function | type |
|-|-|-|
|ConnectCtrl|show a load data dialog|UIControl|
|ExpansionCtrl|expands a graph node on double click|BGControl|
|HighlightNodeCtrl|highlight selected graph nodes|BGControl|
|InfoBoxCtrl|show a infomation box on click on a graph node|UIControl|
|MessageBoxCtrl|show a message box on demand|UIControl|
|RelFinderCtrl|finding relations between graph nodes|BGControl|
|RelFinderDialogCtrl|show a dialog for user to launch a finding task|UIControl|
|SearchBarCtrl|show a search bar for keyword input|UIControl|
|ToolbarCtrl|show a tool bar|UIControl|
### theme
You can set the theme of an app when you create it:
```javascript
igraph.i18n.setLanguage("chs");
var app = new igraph.GraphNavigator(document.getElementById('graphArea'), 'LIGHT');
app.loadGson("honglou.json");
```
Or you can customize the theme according to your own needs:
```javascript
igraph.i18n.setLanguage("chs");
var app = new igraph.GraphNavigator(document.getElementById('graphArea'),{
groups: {
useSeqColors: false,
custom: {
person: {color:'blue'},
location: {color:'red'},
event: {color:'green'}
}
}
});
app.loadGson("honglou.json");
```
Then each type of node will change to the specified color. The parameters of the Theme object are as follows.
```javascript
export interface Theme {
canvasBackground: string,
highlight: {
gradientInnerColor: string,
gradientOutterColor: string,
}
expansion: {
backgroudColorCollapsed: string,
backgroudColorExpanded: string,
fontColor: string
}
edges: object,
nodes: object,
groups?: {
useSeqColors: boolean,
SeqColors?:NodeColor[],
custom?:{}
}
}
```
| Name | Type | Default | Description |
|-----------------------------------|-------------|----------------------------|------------------------------------------------------------------------------------------------------------|
| canvasBackground | String | `"none" ` | Canvas background color |
| highlight.gradientInnerColor | String | `"#00FF00"` | Internal color gradient when node highlights. |
| highlight.gradientOutterColor | String | `"#FFFFFF"` | External color gradient when node highlights. |
| expansion.backgroudColorCollapsed | String | `"rgba(127, 127, 127, 0.9)"` | The color of the tag when node is collapsed. |
| expansion.backgroudColorExpanded | String | `"rgba(0, 128, 0, 0.9)"` | The color of the tag when node is expanded. |
| expansion.fontColor | String | `"#FFFFFF"` | The font color of the tag. |
| edges | Object | `Object ` | All options in this object are explained in [here](https://visjs.github.io/vis-network/docs/network/edges.html).| |
| nodes | Object | `Object ` | All options in this object are explained in [here](https://visjs.github.io/vis-network/docs/network/nodes.html).| |
| groups.useSeqColors | Boolean | `false ` | If true, the node will cycle use the colors in the color sequence. If false, nodes will use custom colors. |
| groups.SeqColors | NodeColor[] | `null ` | The color sequence. |
| groups.custom | Object | `null ` | The custom colors. |
### event handling
MainFrame and controls communicate with applications through events. For example, when the window is resizing, MainFrame and all controls will receive FRAME_RESIZE events.
To subscribe a event, call a `on(event, handler)` method on MainFrame or a Control. To cancel the subscription, use `off(event, handler)` instead.
To fire an event to MainFrame, use `MainFrame.emit(event, args)` or `MainFrame.fire(event, args)` method. Unlike the `emit()` method, `fire()` put default context objects including `mainFrame`, `htmlMainFrame`, `theme` into `args` before emition. To fire an event to a `Control`, use `emit(event, args)` method.
MainFrame loads data via a `Connector` which may connect to a `LocalGraph` or a `RemoteGraph`. A `LocalGraph` loads all data once from a GSON object or file, while a `RemoteGraph` interacts with a remote graph server each time if no cache data is available.
An application always employe an embedded MainFrame to load a GSON file via `loadGson()` method:
```
app.loadGson("honglou.json");
```
Or calling `connect()` method to load an interactive graph from remote IGP server:
```
app.connect("http://localhost:9999/graphserver/connector-bolt");
```
MainFrame loads data from a `LocalGraph` in `GSON` format. `GSON` is actually an enhanced `JSON` format for graph data. The enhancement is `GSON` recoginzes `function`s, which is not valid in JSON.
`GSON` consists of some data items, it is defined as follow:
```typescript
export interface GSON {
"data": {
nodes: object[];
edges?: object[];
}
"dbinfo"?: object;
"categories"?: object;
"translator"?: {
"nodes"?: (node: object) => void;
"edges"?: (node: object) => void;
};
}
```
Here, `translator` defines translator functions for graph nodes and edges, which will be invoked on loading. An example is shown below, in which `description` of each node is evaluated on loading time.
```javascript
"translator": {
"nodes": function (node) {
//set description
if (node.description === undefined) {
var description = "
";
description += "
";
description += "" + node.label + "" + "[" + node.id + "]";
description += "
";
node.description = description;
}
},
}
```
## Datasets
Two GSON datasets are provided in examples as `.json` files: honglou.json, WorldCup2014.json.
The honglou dataset comes from the Chinese famous novel *Dream of the Red Chamber*(also called *The Story of the Stone*, https://en.wikipedia.org/wiki/Dream_of_the_Red_Chamber), in which *Jia Baoyu*, *Lin daiyu*, and *Xue baochai* are famous characters. The honglou dataset defines 300+ entities represent persons, locations, and events in the novel, and 500+ links between them.
nickel2008@github provides this dataset. Maybe there are some mistakes in the dataset, but it is good enough to use as an example graph.
The world cup 2014 data set comes from http://visjs.org/examples/network/exampleApplications/worldCupPerformance.html. The edges in particular (~9200) are very computationally intensive to draw.
The next screenshot shows how WorldCup2014.json is rendered in `GraphNavigator` (empowered by visjs).
An `RemoteGraph` is always provided by an IGP(interactive graph protocol, see https://github.com/grapheco/InteractiveGraph/blob/master/IGP.md) server. To build an IGP server, refer to the InteractiveGraph-neo4j project and other 3-party projects.
