"Design a modern, minimalist logo featuring the letter 'D' that is sleek, bold, and versatile for a media site. The design should be clean and professional, with a balanced combination of negative space and subtle geometric elements. Opt for a flat or slightly dynamic style that conveys innovation and digital engagement. The color scheme should be contemporary, such as black, white, and a pop of vibrant color (e. g. blue, red, or gradient effects) to enhance visibility. The logo should work well across various digital platforms, including websites, apps, and social media. "
