Summary and Visualization of Total Group Expenses and Individual Balances

[Mari618]

As a member of a group managing shared expenses, I want to view a summary of the total group expenses and individual balances for each participant, so that I can easily understand the overall financial status of the group and see how much each participant owes or is owed.

Acceptance Criteria:
Group Expense Summary:

• The system should provide a summary view showing the total amount of expenses for the entire group.
• This summary should include details such as the total amount spent, total amount each participant has contributed, and the overall balance.

Individual Balances:

• For each participant, the summary should display their individual total contributions, amounts owed to others, and amounts they are owed.
• The balance for each participant should be calculated based on their contributions and the share of each expense.

Visualization:

• The summary view should include visual elements such as charts or graphs to help users easily understand the financial breakdown. Examples include:
• A pie chart showing the percentage of total expenses each participant contributed.
• A bar graph displaying the total amount spent by each participant.
• Visual elements should be interactive, allowing users to click for more detailed information if needed.

Validation:

• The system should validate that the total amount of individual balances matches the total group expenses, ensuring accuracy in the summary.
• Any discrepancies or errors in calculations should be flagged with a clear error message, and users should be able to review and correct the issue.

Real-Time Updates:

• The summary view should update in real-time as new expenses are added, modified, or deleted, ensuring that users always see the most current information.

User Interface:

• The summary and visualization should be presented in a user-friendly and intuitive layout.
• Clear labels and descriptions should be provided to help users understand the data and visuals.
