Who appears — the searched person's direct SFC colleagues: individuals who held an SFC licence at one or more of the same firms during overlapping periods. Lines between colleagues mean they also once shared a firm (even one the searched person was never at).

How colleagues are ranked — each one gets a tie‑strength score, summed across every firm they share with the searched person. For each shared firm:

• Days of overlapping tenure at that firm — longer shared time means a stronger tie.
• Firm size penalty — sharing a boutique means more than sharing a megacorp, so the contribution is divided by log(firm_size + 2).
• Licence activity match — two people who both do e.g. Dealing and Advising at the same firm are more likely to have actually worked together. We add the Jaccard similarity of their activity sets.

Formula: score = Σfirm overlap_days × (0.5 + activity_jaccard) ÷ log(firm_size + 2)

Only the top 200 colleagues by score are drawn so the graph stays legible. Hover any node to see its score and rank; click to re-center the network on that person. “Active only” restricts to currently-licensed relationships.
