This is the explanation for the outcome of the participatory budgeting election decided using the Greedy Utilitarian Welfare algorithm.
Some of the key features of the election are: The election has a total budget of {{ "{:,}".format((budget | int)) }} {{ currency }} of which {{ "{:,}".format((spent | int)) }} {{ currency }} was spent. The election had a total of {{total_votes}} voters. Note that each participant can vote for multiple projects. Therefore, the total votes for all projects may be higher than {{total_votes}}
This page shows and explains the outcome of the election. The first graph shows the satisfaction scores for the projects and allows you to filter and examine the data in greater detail. The bars show the budget at each stage of the election and the projects selected or rejected in each round. Finally, the final bar chart shows an overview of the selected and rejected projects.

To view the list of the projects selected, click this:

The chart above shows the satisfaction measures for each project. To investigate further, you can filter the bar chart by selected or rejected projects, and sort by name, cost or satisfaction score. Use the dropdowns above to filter and sort the data.

Round by Round Analysis

The following section of the visualisations allows you to click through 'round by round' of this section of the election. It shows at each point the remaining budget, and the projects with the highest satisfaction up to the selected project. The selected project is shown in green, and any rejected projects are shown in red. A project will be shown in red if it is the next most popular project however there is not enough budget remaining to purchase the project. This means, the next most popular project will be considered - and so on until a project is found that can be purchased with the remaining budget. Use the previous and next round buttons to move through the different rounds of the election.

The chart above shows the current budget of {{ "{:,}".format( (round.remaining_budget | int) ) }} {{ currency }}. Various other projects were rejected in this round, even though they had a higher or equal satisfaction score than the selected project which had a score of {{projects[round.selected_project.id]["votes"]}}.

{% else %}

The chart above shows the current budget of {{ "{:,}".format( (round.remaining_budget | int) ) }} {{ currency }}. {{ round.rejected_projects[0].id }}: {{ projects[round.rejected_projects[0].id]["name"] }} was rejected in this round, even though it had a higher or equal satisfaction score than the selected project which had a score of {{projects[round.selected_project.id]["votes"]}}.

{% endif %} {% else %}

The chart above shows the current budget of {{ "{:,}".format( (round.remaining_budget | int) ) }} {{ currency }}, and the selected project "{{ projects[round.selected_project.id]["name"] }}" with cost {{ "{:,}".format( (round.selected_project.cost | int) ) }} {{ currency }}. The selected project was chosen because it had the highest satisfaction score ({{projects[round.selected_project.id]["votes"]}}) and was within budget.

{% endif %}

{% endfor %}

The chart above shows a colour coded bar chart, which shows the selected projects in order. Red for selected, green for rejected. This is a quick over-view visualisation showing that it is not always the most popular project which is selected, but the most popular projects within budget.
