Let's run your graph through a filter so we can all read it:
$ awk <<__HERE__ \
> '{printf("%s %s ",$1,$2); i=($2-14)*50; i=int(i); while (( --i > 0 )) printf("*"); printf("\n");}'

1998 ***************************
1999 ***************
2000 ***************
2001 ***********************
2002 ***************************

Good luck fitting a straight line to that!
Now, if 1998 is an outlier (could be determined from
earlier data), than your trend line looks reasonable.
Still, the curve might be peaking in 2002.
If 1999 and 2000 are the outliers, then I would say
you are the one in error.
Not that seeing trends on this short a sequence of
data is anything other than reading tea-leaves.
