Create a clean and modern SVG vector logo for a personal finance web application. Use a pure white background and green line art only (#22C55E or similar). The design should be minimalistic, scalable, and suitable for a SaaS product. Incorporate subtle elements that symbolize budgeting, savings, expense tracking, financial growth, and money management, such as upward trend lines, wallets, charts, coins, or a simplified dashboard interface. Use smooth, consistent stroke widths and avoid gradients, shadows, fills, 3D effects, text, or complex details. The logo must be recognizable at small sizes, professional, modern, and optimized as a clean SVG icon.
