Today’s Project

Welcome to the finale! We’ve built a journal with AI analysis. Today we’re creating a beautiful Streamlit dashboard with mood charts, word clouds, and AI-generated monthly summaries!

You’ll visualize your emotional journey and discover patterns you never noticed!

Project Task

Create a Streamlit insights dashboard with:

• Mood-over-time line chart (interactive with Plotly)

• Word cloud from all journal entries

• Monthly summary cards (AI-generated)

• Theme frequency chart

• Entry statistics and streaks

• Export insights as PDF

• Beautiful, intuitive interface

This project gives you hands-on practice with Streamlit, data visualization, Plotly charts, word clouds, dashboard design, and building data-driven applications — essential skills for analytics and insight tools!
