org.from_csv("employees.csv", name="name", manager="reports_to")
org.generate().save("org_chart.png")

# From nested dictionary
org = OrgChartGenerator()
org.from_dict({
    'name': 'CEO',
    'children': [
        {'name': 'CTO', 'children': [{'name': 'Dev Lead'}, {'name': 'QA Lead'}]},
        {'name': 'CFO', 'children': [{'name': 'Controller'}]}
    ]
})
org.layout("top-down").generate().save("hierarchy.png")

API Reference

Initialization

org = OrgChartGenerator()

Data Input Methods

# From CSV with name and manager columns
org.from_csv(
    filepath="employees.csv",
    name="employee_name",
    manager="reports_to",
    title="job_title",        # Optional
    department="dept",        # Optional
)

# From JSON file (nested structure)

org.generate().save("board_structure.png")

Node Display Format

By default, nodes display:

  • Name (required)

  • Title (if provided)

Example node appearance:

┌─────────────┐
│  John Smith │
│    CEO      │
└─────────────┘

Dependencies

graphviz>=0.20.0
pandas>=2.0.0

System Requirement: Graphviz must be installed on the system.

  • macOS: brew install graphviz

  • Ubuntu: apt-get install graphviz

  • Windows: Download from graphviz.org

Limitations

  • Very large org charts (100+ nodes) may be hard to read

  • Photo support requires external image files

  • Node positions are auto-calculated (limited manual control)

  • Complex reporting relationships (matrix orgs) not well supported
