Create a global population density map using a gradient color scheme that ranges from light peach for low density to deep red for high density. Instead of showing "persons per square KM," label the density categories as "Estimated Population Density." Use bolder lines to delineate continents and remove any brand logos. Adjust the background to a soft cream color for contrast and clarity. Include a sidebar legend with a simplified scale: "Very Low," "Low," "Medium," "High," and "Very High" density, each with corresponding gradient shades.
