Projects/Where Does My Money Go/Model
From Open Knowledge Foundation
This document describes in summary terms the interactive visualization planned for the Where Does My Money Go? project. Our intention is to keep the model simple, usable and scalable, and features are defined with this principle in mind.

Available data
Data is divided up into regions, functions, and sub-functions. We want to show relative budgets by region and function. The trick is to draw comparisons between multiple dimensions in as simple a way possible. We intend to combine four different models, presented concurrently.
Concept should allow drill-down to:
- functions by proportion, by region
- sub-functions of functions
Concurrently, the visualization should show expenditure over time, as time-series graphs and animations as necessary.
Visualization
A geographical map to show regional divisions
- Map forms the basis for regional divisions. England is divided into 9 regions, see below.
Use the map as cartogram to show how budget is divided, per capita.
- Bubble chart on map shows relative budget for region.
On drill-down into sub-function
- Select a single function
- Display sub-functions and relative proportions.
On filter by comparative function
- Select more than one function variable
- express comparison in pie charts by region
Combined data for time series
- 4 stacked bar graphs by region(??) of selected variables for whole time series concurrent with the map, to display variation with time.
Interactivity
Filter by function
Use checkboxes for initial filter by function, see below.
Drill-down on sub-function
When only one function is selected, drill-down to sub-function will be possible.
Affordances (EITHER/OR)
- drill-down into sub-function
- drill-down into English regions
Comparison by function and region
When more than one function is selected, bubbles can be displayed as pie charts, showing relative expenditure. This comparison works on regional drill-down throughout England.
Timeline control
A timeline slider to navigate/animate the cartogram over the relevant time period. This should tie in with the time series bar chart.
