Task 3: Practice Exercise

Story:

Here we are looking into an automobile dataset which has various attributes like drive-wheels,body-style and price.

Lets view the snapshot of our selected dataset.

Here let's say we are selecting 3 important features drive-wheels, body-style and Price.

• The possible values of drive-wheels are 4 wheel Drive(4wd),Front WheelDrive(fwd) and Rear wheel Drive(rwd).

• The different body styles of the cars are hardtop,sedan,convertible and so on.

There are 2 types of people here:

• A customer who wants to purchase the cars with less price , different body styles and wants to look for the drive wheel with this arrangement.

• A dealer who wants to showcase the prices for the cars with different body styles and drive wheels.

• As a data analyst, you have been given a task to visually show the body-style and prices with respect to each drive wheel selected.

• So ideally you want to showcase this in the form of 2 interactive charts such as pie chart and bar chart on selection of drive wheel.

Components of the item

1. Drive Wheel Type

   For the chosen Drive wheel,

   • Pie Chart showing body style and price.

   • Bar Chart showing body style and price.

Below is the key item,

• Drive wheels

Requirements to create the expected result

• A dropdown menu: For choosing Drive wheel type
• The layout will be designed as follows:
• An outer division with two inner divisions (as shown in the expected layout)
• One of the inner divisions will have information about the dropdown(which is the input) and the other one is for adding graphs(the 2 output graphs).
• Callback function to compute data, create graph and return to the layout.

To do:

1. Import required libraries and read the dataset
2. Create an application layout
3. Add title to the dashboard using HTML H1 component
4. Add a dropdown using dcc.dropdown
5. Add the pie chart and bar chart core graph components.
6. Run the app
