PyGraphistry Core

Doc routing (local + canonical)

• First route with ../pygraphistry/references/pygraphistry-readthedocs-toc.md.
• Use ../pygraphistry/references/pygraphistry-readthedocs-top-level.tsv for section-level shortcuts.
• Only scan ../pygraphistry/references/pygraphistry-readthedocs-sitemap.xml when a needed page is missing.
• Use one batched discovery read before deep-page reads; avoid cat * and serial micro-reads.
• In user-facing answers, prefer canonical https://pygraphistry.readthedocs.io/en/latest/... links.

Quick workflow

1. Register to a Graphistry server.
2. Build graph from edges/nodes (or hypergraph from wide rows).
3. Bind visual columns as needed.
4. Plot and iterate.

Minimal baseline

import os
import graphistry

graphistry.register(
    api=3,
    username=os.environ.get('GRAPHISTRY_USERNAME'),
    password=os.environ.get('GRAPHISTRY_PASSWORD')
)

Auth variants (org + key flows)

# Organization-scoped login (SSO or user/pass org routing)
graphistry.register(api=3, org_name=os.environ['GRAPHISTRY_ORG_NAME'], idp_name=os.environ.get('GRAPHISTRY_IDP_NAME'))

# Service account / personal key flow
graphistry.register(
    api=3,
    personal_key_id=os.environ['GRAPHISTRY_PERSONAL_KEY_ID'],
    personal_key_secret=os.environ['GRAPHISTRY_PERSONAL_KEY_SECRET']
)

# edges_df: src,dst,... and nodes_df: id,...
edges_df['type'] = edges_df.get('type', 'transaction')
nodes_df['type'] = nodes_df.get('type', 'entity')
g = graphistry.edges(edges_df, 'src', 'dst').nodes(nodes_df, 'id')
g.plot()

Hypergraph baseline

# Build graph from multiple entity columns in one table
hg = graphistry.hypergraph(df, ['actor', 'event', 'location'])
hg['graph'].plot()

ETL shaping checklist

• Normalize identifier columns before binding (src/dst/id type consistency, null handling).
• Prefer a plain type column on both edges and nodes for legend-friendly defaults and consistent category encodings.
• Deduplicate high-volume repeated rows before first upload.
• Materialize nodes for node-centric steps:

g = graphistry.edges(edges_df, 'src', 'dst').materialize_nodes()

Practical checks

• Confirm source/destination columns are non-null and correctly typed.
• Materialize nodes if needed (g.materialize_nodes()) before node-centric operations.
• Start with smaller slices for first render on large data.
• For neighborhood expansion and pattern mining, always use .gfql([...]) or .gfql("MATCH..."). The methods hop() and chain() are deprecated.
• Keep credentials in environment variables only; do not hardcode usernames/passwords/tokens.
