Prompt
"Create an image representing Keynesian economics, a macroeconomic policy that focuses on aggregate demand and government intervention. Depict a graph showing an upward-sloping aggregate demand curve intersecting with a downward-sloping aggregate supply curve, with a subtle background image of a bustling economy, such as a cityscape or a factory. Incorporate visual elements that convey the concepts of multiplier effect, liquidity preference, and deficit spending, such as ripples in water, coins, or a government building in the background. The style should be a mix of modern and vintage, reflecting the evolution of Keynesian economics over time. The color scheme should be a combination of blues and greens, representing stability and growth."
