A horizontal bar plot is a plot that presents quantitative data with rectangular bars with lengths proportional to the values that they represent. Bar charts are used to display categorical data. For datasets where 0 is not a meaningful value, a point plot will allow you to focus on differences between levels of one or more categorical variables. We access the sex field, call the value_counts method to get a count of unique values, then call the plot method and pass in bar (for bar chart) to the kind argument..
