Set phrase: 宏图大志 (grand vision and lofty ambition) and 大展宏图 (to unfold one's grand plans / spread one's wings) - the latter is a classic congratulatory line in business or career contexts.
memory
宏 (grand, vast) + 图 (plan, map) - a vast map / a grand blueprint. Think of unrolling a huge architectural drawing across a table.
