PDF calcutaion and graphs

I have different types of datasets, by looking at the data set we can not tell what type of distribution it has. so, how can I plot the probability density function? Ex: x =

    53
    70
    71
    72
    73
    75
    76
    76
    77
    77
    77
    77
    77
    78
    79
    79
    79
    80
    80
    80
    80
    80
    81
    81
    82
    83
    83
    83
    84
    85
    85
    86

would be grateful if anyone can suggest a method. Thanks in advance.
