Create a background banner for a B2B lead generation website popup. The background should have a professional and modern design with abstract graphics that subtly convey themes of business connection, growth, and efficient communication. Use a blend of soft blue and gray tones with a slight gradient for depth, ensuring that the background complements the contact form overlay without being overwhelming. Include simple icons or shapes like graphs, lines, and connection symbols to represent data flow and growth in a clean, uncluttered way, while keeping the focus on readability, use declinaisons of red and white colors --ar 16:9
