Summary

Stakgraph will add a monthly earnings bar chart to the /leaderboard page, positioned below the Top3 section. This chart will visualize total earnings per month, aggregated using the paid_date field from the Bounty struct, to provide users with a clear view of monthly payout trends.

Planned Changes

• Create a new React component to render a bar chart of monthly earnings.
• Fetch bounty data from the /people/bounty/leaderboard backend endpoint.
• Aggregate earnings by month using the paid_date field and sum the price values.
• Insert the chart directly below the Top3 section on the /leaderboard page.

Files/Areas Affected

• /src/pages/leaderboard/index.tsx (LeaderboardPage component)
• New chart component (location TBD, likely under /components)
• Data fetching logic for bounties (may reuse or extend existing hooks/services)

Note: Chart will accurately reflect monthly earnings based on backend data and will be visually integrated below the Top3 leaderboard section.
