Narrative:

Ground cleared me to taxi runway 22 on taxiway D. I was unfamiliar with the airport and referred to my airport diagram, which indicated a leg of some distance from taxiway D to runway 22. My intent was to taxi onto this leg and hold at the line and then contact tower. I did not see the hold short line because I was not expecting it. I believe this leg does not exist. When I saw the taxiway D converging to the runway I stopped. I estimate I stopped 1/2 way between the hold short line and the runway. Factors: unfamiliarity with airport, taxiway not as charted.
