What attractions, if any, are in Dupont Circle in Washington, D.C.?

I'm chaperoning my little brother's trip to D.C., and I want to see the Gandhi statue in Dupont Circle. I don't know the list of stops yet, so I can't know for sure, but I'd like to know if there are any attractions in Dupont Circle that might be on our list?|||To name a few in the Dupont Circle area: The Phillips Collection (1600 21st Street NW); The Textile Museum (2320 S Street NW); Christian Heurich Mansion (1307 New Hampshire Avenue NW); Woodrow Wilson House (2340 S Street NW); and the National Geographic Museum at Explorers Hall (17th and M Streets NW).
