I want to receive information about process diagram (marking, sequence of steps) through Bonita API and save in svg.
This is a feature of the Subscription Model and is not available in Community.
That being said I can imagine a scenario whereby for a case you could do the following (in pseudo code):
get case
getActivities (API)
getArchivedActivityInstances (API)
then sort them into order and create your own HTML that can display an SVG diagram of the process.
reference here

I’ve developed some code that gets the process information as follows,
- Start
- End
- Processes (operations)
- Conditions (gateways)
- Transitions
The numbers are the respective items id’s and the output is shown here:
7533755246857467906=>start: Start1
5056439953452068172=>end: End1
5282329866329449709=>operation: getActivitiesForDiagram1
5072827248852522222=>operation: getActivitiesForDiagram2
8304515131711232508=>operation: getActivitiesForDiagram3
7421274932560925310=>operation: Step1
8048306028807336420=>condition: Gateway1
8593787269775937543=>condition: Gateway2

You will have to work out how to “develop” the solution for your chosen flow-charting software, from here it should be quite easy. However I hope you will also share it 
From here it should be easy to develop something that gets the status and colours the flow diagram appropriately.
To execute add a Script Connector to an activity, copy the code and execute, it will work for the current process. I’ve not created to to work for a particular case etc.
You can then look at your log to see the printed output, how you then use it is up to you.
