Graph Chart
A graphical chart is a visual representation employed to depict the connections between sets of two points. The points themselves are illustrated as nodes or vertices, which are connected by lines
Configuration
Option
Provide the JSON content to generate the chart dynamically. Sample data is given blow.
{
"categories": [
{
"name": "Nodes"
},
{
"name": "Edges"
}
],
"nodes": [
{
"name": "Node 1",
"category": 0
},
{
"name": "Node 2",
"category": 0
},
{
"name": "Node 3",
"category": 0
},
{
"name": "Node 4",
"category": 0
}
],
"links": [
{
"source": "Node 1",
"target": "Node 2",
"category": 1
},
{
"source": "Node 2",
"target": "Node 3",
"category": 1
},
{
"source": "Node 3",
"target": "Node 4",
"category": 1
}
]
}The JSON data will have two categories: 1. Nodes, 2. Edges.
This is followed by the set of nodes - in which - each node consists of "name" and "category" where the "category" is mentioned by its index number.
The user needs to provide the set of links after nodes. Each link needs to be defined with a source node and a target node. The category is mentioned by its index number.
Title
Provide a short and descriptive title for the chart that clearly summarizes the data and information being presented. This title should be concise yet informative, helping the audience understand the content of the chart at a glance.
Tooltip
This tooltip pops up when the user moves the mouse over the block area of the chart. This is commonly used to provide some extra or important information to the user on the usage of the widget.
The tooltip will be immediately shown when the user's mouse hovers over the widget, and immediately hides when the user's mouse leaves. This information will be contextual, useful, and informative.
