Design a minimalistic Fiverr gig cover image for a professional data analysis service. The design should feature a clean white background with accents of blue and green to signify trust and technology. Include sleek, modern icons or elements representing Excel, SPSS, and STATA, such as a simple spreadsheet, a pie chart, or a bar graph. The layout should be uncluttered, with a focus on symmetry and balance. The text 'Data Analysis Expert' should be prominent, using a bold, modern font in dark blue or black for contrast. Add a subtle tagline beneath, like 'Transforming Data into Insights,' in a lighter font. Incorporate soft shadows or gradients for a polished look, while ensuring the overall aesthetic remains minimal and professional. Avoid excessive details, keeping the design clean and appealing for a professional audience.
