Making sense of densely-connected data can be challenging and time-consuming. This demo shows how combo features can reveal hidden patterns quickly and easily, even in complex networks.

The dataset contains details of suspected terrorists and their country and region of origin. The initial chart presents a tangled web of connections, and it’s difficult to spot key relationships.

Combos reduce clutter

When you combine nodes by region and country, it creates a high-level view and the visualisation starts to make sense:

• Link widths between combos change automatically to show which regions or countries have more connections between them.
• Double-click a region to drill down further. The nested combos represent suspects from each country.
• Double-click a country to see its network of individual suspects.

Combos let you move around the chart more easily without losing any of the detail you'd get from an uncombined view.

Revealing suspects

A chart of combos isn’t just for high-level analysis.

Double-click a country and click on a suspect to reveal their primary connections across the chart. Nodes linked to them are brought to the foreground, so it’s easier to analyse key suspects without distraction. You can select multiple suspects to foreground a subset of interesting data.
