Visualizing data in Node Graph format

You can generate Node graph panel data with CSV, JSON or XML feature of Infinity data source.

From v0.8.0, we have out of the box support for node graph. Prior to v0.8.0, you can use “Table” format to create node graph with limited options.

Irrespective of the version, you need two queries to form a Node graph visualization.

  1. First query which lists the nodes. Should have mandatory id and title field. This also can have additional arc__* fields to specify the arcs value for the node.
  2. Second query which list the edges (relations). Should have three mandatory fields namely id, source and target

Node Graph format

From v0.8.0, infinity plugin have dedicated support for node graphs. You need to create two different queries with the format of nodes and edges for each query.

Nodes

Nodes query should have following fields.

  • id*
  • title
  • subTitle
  • arc__*
  • detail__*

If you have any arc__* field, corresponding value (number) will be used as the nodes arc value. Note : Total value of row item should sum to 1. If you need to specify a color for the arc__* field, add a new field called arc__*_color.

Edges

Edges query should have following fields.

  • id*
  • source*
  • target*
  • detail__*

works same as Nodes. But doesn’t support arc__* fields.

Example

Below is an example of nodes query

Below is an example of edges query

Corresponding Node Graph is given below

Corresponding CSV data is given below

Nodes :

csv
id,title,sub-title,cpu,memory,c_disk_size,d,c_disk_size color,d color,detail__hello
A,Server A,Application Server,12,10,0.1,0.9,blue,red,world
B,Server B,DB Server,90,87,0.1,0.9,blue,red,hello
C,Server C,Application Server,20,23,0.20,0.80,blue,red,hello
D,Server D,Middleware Server,47,98,0.90,0.10,blue,red,world

Edges :

csv
id,source,target,mainStat,secondaryStat,detail__one
1,A,B,30,mb/s,abc
2,A,C,20,mb/s,def
3,B,D,24.2,mb/s,ghi

Some of the fields of the CSV doesn’t match the node graph format. So we used column alias to match the exact field. Also for CSV format, number formats needs to set explicitly. Otherwise, they will be rendered as string.

finally, the panel json looks like this
