+/// A component that displays the total number of tickets per user.
+///
+/// This component takes lists of [`UserPartial`] and [`TicketPartial`] items to calculate
+/// and display the total number of tickets submitted by each user.
+/// The results are presented in a sorted list with a bar chart visualization.
+///
+/// # Props
+/// - `users`: A `Vec<UserPartial>` containing partial user data.
+/// - `tickets`: A `Vec<TicketPartial>` containing partial ticket data for analysis.
+///
+/// # Functionality
+/// - **Maps User Names**: Creates a map from user IDs to their first and last names for display.
+/// - **Calculates Totals**: Aggregates ticket counts for each user.
+/// - **Sorts Results**: Displays users sorted by their ticket count in descending order.
+/// - **Visualizes Data**: Renders a bar chart where the width of each bar is proportional
+///   to the ticket count for that user, relative to the user with the maximum tickets.
+/// - **Name Formatting**: Uses the [`dequote!`] macro to clean up user names before display.
+///
+/// # Example
+/// ```rust
+/// html! {
+///     <UserTotal users={my_user_partials} tickets={my_ticket_partials} />
+/// }
