Predictive models often use multiple input features to generate a prediction about something. For example, the various characteristics about passengers on the Titanic ship can be used to generate a model that predicts the probability that any particular passenger survived or perished. This visualisation demonstrations how a breakdown plot can be used to examine and understand how the various characteristics of passengers contributed towards the model's prediction of their probability of survival.

The sankey chart is a powerful tool for visualising the flow of any quantitative commodity from its source to its destination. Great candidates for this include energy or water (which is used here). In this chart, a user can see how the distribution of water is split at various stages, and how much is lost at different points. This could help a governing body to target key areas where losses can be reduced or identify utilities that are being over or underutilised.

One type of visualisation that can be used to show the breakdown of hierarchies in data is the sunburst chart. Each ring corresponds to a level in the hierarchy, and each segment in a ring represents a group at a level. This visualisation demonstrates how a sunburst chart can be used to visualise the breakdown of the New Zealand workforce into industry groups, starting from high level industry groups and diving down into more specialised groups. The size of each ring segment in the chart is proportional to the size of the industry group relative to the total workforce. Data is based on the 2018 New Zealand Census.
