[Feature Request] Add Export Reports & Data Download Functionality

[Riya-Kharade]

💡 The Problem

Currently, EcoPulse allows users to visualize and compare pollution data,
but there is no way to export or download reports.

Users cannot:

• Download pollution reports as PDF
• Export charts as image files
• Download raw data in CSV format

This limits usability for research, academic, and presentation purposes.

🚀 Proposed Solution

Implement an export feature that allows users to download pollution insights and datasets.

The feature should include:

• 📄 Download pollution report as PDF
• 🖼 Export charts as PNG image
• 📊 Download dataset as CSV file

This functionality will enhance usability and make the platform more professional.

🎨 Visual Representation

Add export buttons in:

1️⃣ Analytics Dashboard (analytics.html)

• "Download PDF Report"
• "Export Chart as PNG"
• "Download CSV"

2️⃣ Comparison Dashboard (dashboard.html)

• Export comparison chart
• Export filtered dataset

Buttons should:

• Match eco-theme styling
• Include icons
• Have hover transitions

🛠️ Implementation Details

• Use JavaScript-based PDF generation (e.g., jsPDF or HTML-to-canvas)
• Use Chart.js built-in toBase64Image() for PNG export
• Generate CSV file dynamically from dataset
• Add export button components
• Ensure exported files reflect selected filters

Files likely affected:

• analytics.html
• dashboard.html
• sample-data.json

No backend required.

🎯 Impact

This feature will:

• Improve research usability
• Enable academic and presentation use cases
• Enhance enterprise-level feel
• Increase production readiness
• Strengthen hackathon and portfolio value

It transforms EcoPulse from a visualization tool into a report-ready environmental analytics platform.
