Question
In Python code:
Process:
The user (client) requests data from the (server)
DataFile:
USAStates2020.csv
User Layer:
The user selects a country, and passes the country name to the Business Layer. Use TKinter to produce a UI for the user to select a country. Send the selected country to the Business Layer.
Business Layer:
Receives the information from the User Layer and constructs a SQL query to send to the Data Layer. The query extracts the yearly data (1970,2020) for the requested country. The data may be queried either country year-by-year or in one query for year range. After receiving the JSON string back from the Data Layer, send the data to the Graphic Layer for plotting.
Data Layer:
Construct a SQL Database based on the data from the DataFile. Processes the queries from the Business Layer. Sends back a JSON string for the requested query.
Graphic Layer:
Create a graphics class to plot the MatPlotLib XYPlot.
Server Layer:
The database access is controlled by the Server Socket. The client sends a query, and the server sends a JSON string.
Client Socket:
Requests data from the server. After receiving the data from the server, the client displays the data.

Hello, Im completely lost with my coding assignment. Here are the instuctions: Summary Kidder Garden Pete Burnham of the Kidder Garden website wants you to develop an application for drawing images or "stamps". As a proof of concept, he wants you to create a webpage in which users can choose stamps of a specified size and shade (opacity) and then place those stamp images on a canvas using the mouse. The user can then modify the size, position, rotation, or shading (opacity) by clicking tools from a toolbar and applying that tool to a stamp image. Pete has already designed the webpage. He needs you to write the code to create the stamp objects and place them as images on the page's canvas. Figure 14-50 shows a preview of a completed page with stamp images created and modified by the user. Pete has also supplied you with the following object methods that will be useful to you: The elementX() method for the Event object prototype that returns the x-coordinate of a mouse…arrow_forward
