A simple Facebook messenger bot. Records chat history (not message contents) and provides useful functionality such as returning user statistics. Built using Node, Facebook-chat-api, Node-canvas, and a ChartJS wrapper for Node-canvas.

• $ || $help responds with message describing all commands available to users, and corresponding examples.
• $stats <target> responds with individual user statistics. Dataset includes messages sent and reactions (sent and received).
• $stats <target> draw responds with group chart, or individual user chart if valid target is provided.

Current Features:

• Accept commands using $<command> [target] [options].
• Record thread history (since bot invitation), then process each message and update data model. Process occurs on startup, on each bot command.
• Return user statistics.
• Return server rendered chart image of group statistics.

Planned Features:

• Return server rendered chart of specific statistics and individual user data sets.
• Reminder function that will send a message containing a reminder to chat on time condition. The reminder is written by the user who sets the command.

Below shows user's total share of messages in group chat and the exact timestamp of the chart creation. Invoked by using $stats draw. The graph will be improved upon to make information more concise and visually appealing.
