# Chapter 9 — Visualisations and Reports

## Purpose

This chapter introduces the reporting and visualisation capabilities used to review fraud outcomes and operational trends.

## What this area supports

Visualisations help users understand patterns in the data, such as:

- trends in approvals and declines;
- the effect of rules or models over time;
- mapping or chart-based reporting for operational analysis.

## Common report and visualisation capabilities

- Visualisation recall
- Visualisation registry
- Visualisation parameters
- SQL-based grid generation
- Chart generation
- Map generation
- HTML rendering
- Logging within visualisation data sources

## Example usage

Example: if the fraud team wants to review whether a new rule increased review volume, use the report or visualisation layer to compare the trend before and after the change.

## Operational guidance

- Use visuals to support investigations rather than replace case review.
- Check the data source and parameters before trusting a chart or report.
- Use reports as a complement to manual case review and score analysis.

## Notes

Visualisations make operational trends easier to understand, especially when teams need to explain the impact of changes to stakeholders.
