## Instructions
Create a chart similar to `examples/Figure_1.png`, where we show the counts of good and bad outcomes for the `cholesterol`, `gluc`, `alco`, `active`, and `smoke` variables for patients with `cardio=1` and `cardio=0` in different panels.
By each number in the `medical_data_visualizer.py` file, add the code from the associated instruction number below.
1. Import the data from `medical_examination.csv` and assign it to the `df` variable
1. Import the data from `medical_examination.csv` and assign it to the `df` variable.
2. Add an `overweight` column to the data. To determine if a person is overweight, first calculate their BMI by dividing their weight in kilograms by the square of their height in meters. If that value is > 25 then the person is overweight. Use the value `0` for NOT overweight and the value `1` for overweight.
3. Normalize data by making `0` always good and `1` always bad. If the value of `cholesterol` or `gluc` is 1, set the value to `0`. If the value is more than `1`, set the value to `1`.
4. Draw the Categorical Plot in the `draw_cat_plot` function
4. Draw the Categorical Plot in the `draw_cat_plot` function.
5. Create a DataFrame for the cat plot using `pd.melt` with values from `cholesterol`, `gluc`, `smoke`, `alco`, `active`, and `overweight` in the `df_cat` variable.
6. Group and reformat the data in `df_cat` to split it by `cardio`. Show the counts of each feature. You will have to rename one of the columns for the `catplot` to work correctly.
7. Convert the data into `long` format and create a chart that shows the value counts of the categorical features using the following method provided by the seaborn library import : `sns.catplot()`
8. Get the figure for the output and store it in the `fig` variable
9. Do not modify the next two lines
10. Draw the Heat Map in the `draw_heat_map` function

8. Get the figure for the output and store it in the `fig` variable.
9. Do not modify the next two lines.
10. Draw the Heat Map in the `draw_heat_map` function.
11. Clean the data in the `df_heat` variable by filtering out the following patient segments that represent incorrect data:
- diastolic pressure is higher than systolic (Keep the correct data with `(df['ap_lo'] <= df['ap_hi'])`)
- height is less than the 2.5th percentile (Keep the correct data with `(df['height'] >= df['height'].quantile(0.025))`)
- height is more than the 97.5th percentile
- weight is less than the 2.5th percentile
- weight is more than the 97.5th percentile
12. Calculate the correlation matrix and store it in the `corr` variable
13. Generate a mask for the upper triangle and store it in the `mask` variable
14. Set up the `matplotlib` figure
15. Plot the correlation matrix using the method provided by the `seaborn` library import: `sns.heatmap()`
16. Do not modify the next two lines
