Visual Encoding & Comparative Anatomy
A portfolio bubble chart (often modeled after the BCG Growth-Share Matrix) maps business units, products, or investment assets onto a two-dimensional strategic grid. The horizontal and vertical axes represent key strategic dimensions like market growth and relative market share, while the area of each bubble encodes a third variable, such as revenue, investment capital, or total value. This allows decision-makers to segment portfolios into quadrants (like Stars or Cash Cows) to allocate resources effectively. Trendalyzer processes all your portfolio data entirely locally in your browser, guaranteeing complete privacy with zero server uploads.
Input Format & Required Columns
Format input columns for portfolio bubble chart with explicit headers and numerical measurements. Verify that rows represent discrete categories or observations without unformatted symbol artifacts.
Example Comparison Table
| Product line | Market growth (%) | Relative market share | Revenue (millions) |
Best Practices for Category Comparison
- Ensure sufficient visual distinction for portfolio bubble chart marks across standard and high-contrast viewports.
- Align text labels horizontally whenever possible to improve cognitive readability for portfolio bubble chart elements.
- Double-check scale boundaries and zero-anchors before exporting portfolio bubble chart presentation artwork.
- Data shape
- X score, Y score, size, and label columns
- Exports
- SVG, PNG, and Excel data; PowerPoint export is temporarily unavailable pending dependency review.
How it works
You edit a table in this page. The renderer draws an SVG from those rows in your browser, then you can download SVG, PNG, or Excel data. The table is not uploaded to any external processing server.
