A single prompt used with Nano Banana 2 to generate a miniature diorama of a city, making the city 'pop out' from a map. The prompt is designed to be easily customized by changing the city name.

I turned my city into a 3D map.

All I gave Nano Banana 2 was
one single prompt.

Just swap the city name —
{argument name="city name" default="Tokyo"}, {argument name="city name 2" default="Osaka"}, New York,
anywhere you love —

and a miniature diorama
rises straight out of the map.

Dynamic Arguments (2)

#	Argument Name	Default Value
1	city name	"Tokyo"
2	city name 2	"Osaka"
