Accepted answer

In your data you have a data point every 10 years but if I'm reading this correctly your x-value is x: years[j]:

> d3.range(startYear, endYear)
[1950, 1951, 1952, 1953, 1954, 1955, 1956, 1957, 1958, 1959, 1960, 1961, 1962, 1963, 1964, 1965, 1966, 1967, 1968, 1969, 1970, 1971, 1972, 1973, 1974, 1975, 1976, 1977, 1978, 1979, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012]

So, you are plotting x at 1950, 1951, 1952, 1953, instead of 1950, 1960, 1970, etc...

Easy fix is to use d3.range(startYear, endYear, 10), proper fix is to get your x-values from the header of your CSV file.
