[Vanilla] How do I just d/l the demo map and not the whole demo?

I've had all variations of Civ 4 & 5 for some time but I always remember enjoying the Civ 4 demo map when I had the demo.

After getting Civ 4 proper, I removed the demo, as you tend to do but I miss the map.

Is the demo map available seperately for download somewhere so I can play it with the full game? Does someone have it somewhere?
