Poll Visualizations

Pawtograder provides real-time visualizations for poll results, making it easy to share results with your class during a lecture.

Response Dashboard

After creating a poll, you can view results in real-time. The response dashboard includes:

Dashboard Components

Component	Description
Header	Shows poll question, URL, QR code, and controls
Bar Chart	Visual representation of response distribution
Response Count	Total number of responses received
Poll URL	Direct link students can use to respond
QR Code	Scannable code for quick mobile access

Real-Time Updates

The dashboard updates instantly as students submit responses:

• No page refresh required
• Bar lengths animate as new responses come in
• Response counts update in real-time
• Works across all connected instructor devices

info

Real-time updates are powered by Supabase's realtime subscriptions. The dashboard subscribes to response changes and updates the UI immediately when new data arrives.

Bar Chart Visualization

Both single choice and multiple choice polls display results as a horizontal bar chart:

• Each answer option is shown as a separate bar
• Bar length corresponds to the number of responses for that option
• Labels show the option text
• Counts display the number of responses per option
• Colors distinguish between different options

Reading the Chart

For Single Choice polls:

• The total responses equals the sum of all bars
• Percentages will total 100%

For Multiple Choice polls:

• Each bar shows how many students selected that option
• Percentages may exceed 100% (students can select multiple)
• Total responses shows unique students who responded

QR Code Access

Each poll has a unique QR code that allows students to quickly access and respond from their mobile devices.

How QR Codes Work

Feature	Behavior
Class-Specific	The QR code links to your specific course
Latest Poll	Always directs to the newest active poll
Click to Enlarge	Click the QR code to view it in a larger modal

Using the QR Code in Class

1. Create and publish a new poll
2. Navigate to the poll's response dashboard
3. Click the QR code to enlarge it for projection
4. Students scan with their phone camera
5. They're directed to the current poll and can submit their response

note

If the poll has Require Login enabled, students will be prompted to log in before they can submit a response.

Tips for Effective Presentation

Before Projecting

• Test the QR code from different distances
• Ensure the projector resolution shows the chart clearly
• Have a backup plan (URL) if QR scanning fails

During Class

• Allow 30-60 seconds for students to respond
• Watch the response count to know when most students have answered
• Use presentation mode when you want all eyes on the results

Discussing Results

• Point out the most popular answers
• Ask students to explain their reasoning
• Use surprising results to spark discussion

Accessibility Considerations

• Bar charts use distinct colors for each option
• Option labels are displayed as text alongside bars
• Response counts are shown numerically
• QR code has sufficient contrast for scanning
• Poll URL provides text-based alternative to QR code
