caption: The image shows a line graph on a white background with text that reads "Americans' Self-Identification as Lesbian, Gay, Bisexual, Transgender or Something Other Than Heterosexual". The graph is divided into two sections, one for lesbian and one for bisexual, and each section is further divided into subsections, each representing a different gender. The line graph shows a steady increase in the number of Americans' self-identification as lesbian, gay, bisexual, transgender, or something other than heterosexual.
