Analyzing and Visualizing Real-World Data

# Or is it Holiday Effect?

Let's find out if holidays could be the cause. To do this, we will display the dates next to the points.

Tarefa

1. Add a `hue` parameter to the `.scatterplot()` function so that the points will be colored in accordance to the values in the `'Holiday_Flag'` column.
2. Initialize a `for` loop to display the dates next to the points. Iterate over the indexes of `data` using `index` as the dummy variable.
3. Within the loop, use the `.text()` method of `plt` to display text on the plot. The method should have 4 parameters:
• the first is responsible for the x-coordinate of the text, which should be the `index` value of the `'Temperature'` column with a `0.2` offset;
• the second is responsible for the y-coordinate of text, which should be the `index` value of the `'Weekly_Sales'` column;
• the third is the text that should be displayed which should be the `index` value of the `'Date'` column, transformed into a date;
• the fourth is the `color` parameter, responsible for color of the text, which should be `'black'`.
