Used For

• +**Your static Excel charts put executives to sleep in meetings** → Interactive dashboards where they can hover, zoom, and filter data themselves
• +**You're copying Python plots into emails and they look broken** → Professional charts that render perfectly everywhere and share with a link
• +**Your team asks for the same chart with different date ranges 20 times** → Self-service dashboards where they can adjust filters without bugging you
• +Handles 100k+ data points without choking - most tools crash at 10k
• +Connects directly to databases and APIs - updates automatically instead of manual CSV uploads

Best For

• >Your matplotlib plots look like they're from 1995 and nobody can interact with them
• >You're spending 15 hours a week manually updating PowerPoint charts for weekly reports
• >Your team needs dashboards but Tableau costs more than your intern's salary

Not For

• -Pure Excel users who are happy with static charts — the learning curve isn't worth it if you're not sharing interactive stuff
• -Teams under 5 people without regular data presentation needs — you'll hit the free tier limits and pay $15/month for features you rarely use
• -Companies needing on-premise deployment — it's cloud-only, no exceptions

Pairs With

• *Python/Pandas (where you clean and prep the data before feeding it to Plotly)
• *Jupyter Notebooks (for prototyping charts before publishing them to dashboards)
• *PostgreSQL or BigQuery (as the data source that auto-updates your charts)
• *Slack (where your team gets notifications when dashboard data updates)
• *Google Sheets (for quick data uploads when you don't want to write code)
• *AWS S3 (to store larger datasets that would crash the direct upload feature)

The Catch

• !The free tier view limits hit fast if you share publicly — viral dashboards mean surprise upgrade bills
• !Loading slows down noticeably above 500k data points unless you pay for the pro tier
• !No offline mode means no work on flights or when internet dies during your big presentation

Bottom Line

Makes your data clickable so executives stop asking you to remake the same chart 47 different ways.
