According to the author, ‘ggplot is an implementation of the grammar of graphics’ which is a set of rules for producing visualizations of data. In this first plot, we will track the trajectory of life expectancy over time for each country in the data.

1. map year to x and lifeExp to y.
2. use geom_line to show how lifeExp changes over time. (did you notice a mistaken assignment to the y parameter in the book?)
3. use grouping to make each line refer to a specific country in the dataset
4. facet the data on continent
5. try moving the facets around on the page – 5 across and 5 down
6. add a smoother, change the y scale to a log scale and add the dollar sign
7. add the labels as described in the book
8. try using facet_grid
9. be sure that you know what categorical variables, ordered and unordered, are. compare continuous variables.
10. use the glimpse function on the gss_sm data set. Try this gss_sm %>% glimpse(). What do you think the pipe operator (%>%) does?
11. make a smoothed scatterplot of the relationship between age of the respondent and the number of children. What did you learn?
12. facet the result with the sex and race of the respondent (person who respond to the survey)
13. experiment with the alpha attribute
14. experiment with combining attributes in the facet wrapper
15. geom_bar uses count by default
16. describe how the geom_bar used the count function to determine how much water had been used.
17. Use the prop function and group by ‘1’ to show by region
18. show just the religion column in a table
19. create a bar chart showing the frequency of religious distribution in the data
20. use fill to highlight the different religions
21. create a stacked bar chart to show the frequency of religions by region
22. use the position = dodge attribute to create individual religious frequency bars
23. facet the religious frequency chart by region
24. create a histogram showing midwest regions by size
25. experiment with the number of bins in the previous histogram
26. Where does the count variable come from?
27. use subset to show the data in a histogram just from Ohio and Wisconsin
28. create a kernel density plot of the area of the midwest states

Submit a Word document by Sunday at midnight with screen shots of your work and text. Explain what each image is.

Submit screenshots of your successful installation.

Please use the Movielens dataset (you can find it here, see notes below about the data) and use the data to:

1. Create a collaborative filter recommender system
2. After implementing step 1, you will have a train and test dataset. Build a graph for each of the train and test datasets in which users, movies and their genres are connected. In this graph, each user, each movie and each genre has a node representing them. If user A has a rating for movie B then there is an edge in the graph connecting them. Also, if movie B has two genres: Action and Drama, then node B will be connected to nodes Action and Drama. Edges in this graph have no edge weights and no edge directions (this is an unweighted, undirected graph)
   1. What is the movie with the highest degree of centrality in train and in test datasets separately? (you choose which centrality metric is best in this case)
   2. What is the genre with the highest degree of centrality in train and in test datasets separately? (you choose which centrality metric is best in this case)
   3. use your recommender system to predict the ratings for the test dataset. Build a graph for the predictions and answer question 2.2 and 2.1 for this dataset as well

   PS: Build only Collaborative Recommender System

3. NOTES below:
4. When you go to the dataset link, there are 2 datasets, one small (named ml-latest-small.zip) and one a larger, more realistic dataset (named ml-latest.zip). The former is small and your model will suffer from lack of data, don’t use it. The latter is large and so may push your compute power depending on the machine you’re using. The best approach is to use the larger dataset and downsample it. How you do the downsampling, the ratio and the methodology is up to you (you will be asked about your choices during the presentation)
5. Feel free to give insights in comments in Jupyter Notebook

YOU DONT HAVE TO DO THE ENTIRE CODE. ONLY WORK ON QUESTIONS 2.1 and I will provide the dataframe and training and testing of it as well.

Create a website according to the following specification

1. Create a home page about yourself.(The name is Allison)
2. Create links to the following pages
a. Coin tossing game (JavaScript)
b. Use the Date function to display the current date on the page (JavaScript)
c. Use the Date function to calculate and display how many days are left for July 4,
2022 (Independence day) on the page. You need to modify the attached program
as discussed in class (date1.html) (JavaScript)
d. A currency converter to convert US dollars to Canadian dollars (JavaScript, 2 part
form). Use the following exchange rate. Canadian_dollar = 1.3*US_dollar
e. Information about 3 places you would like to visit
2. Have a look at the attached page picture(links1.html), which was discussed in class and
modify it to create links to your five favorite websites. (JavaScript)
3. Do a research on the Internet about the recent developments in the area of web
technology (node.js) and put your response in a word document and create a link to it
from your home page and submit it (approx 200 words). You should submit your home
page and all the other pages mentioned above to the Instructor. You should put all the
pages in a folder and submit it.

4. Do a research on the Internet about MySQL database and put your response in a word
document and create a link to it from your home page and submit it. (Approx 200 words)
You should design the pages appropriately adding images, graphics and appropriate
colors and design to make the pages attractive and presentable. Also appropriate data
validation should be performed on the data entered.

I need help combining the two projects below and submitting them as one single application project 

Using Windows Form Visual Studio 2019. C#

Person and Customer Classes

Design a class named Person with properties for holding a person’s name, address, and telephone number. Next, design a class named Customer , which is derived from the Person class. The Customer class should have a property for a customer number and a Boolean property indicating whether the customer wishes to be on a mailing list.  Demonstrate an object of the Customer class in a simple application.

PreferredCustomer Class

A retail store has a preferred customer plan where customers can earn discounts on all their purchases. The amount of a customer’s discount is determined by the amount of the customer’s cumulative purchases in the store as follows:
• When a preferred customer spends $500, he or she gets a 5 percent discount on all future purchases.
• When a preferred customer spends $1,000, he or she gets a 6 percent discount on all future purchases.
• When a preferred customer spends $1,500, he or she gets a 7 percent discount on all future purchases.
• When a preferred customer spends $2,000 or more, he or she gets a 10 percent discount on all future purchases.
Design a class named PreferredCustomer , which is derived from the Customer class you created in Programming Problem 4. The PreferredCustomer class should have properties for the amount of the customer’s purchases and the customer’s discount level. Demonstrate the class in a simple application.

I would prefer the application to be interactive and use a TabControl to make it interactive and use a similar coding to what I’m use to so I can use it as a reference for my final project.

1. Write a C++ program that reads in the length and width of a rectangle and prints the area and the perimeter of that rectangle. Area of a rectangle is equal to the length multiplied by the width. The perimeter of a rectangle is equal to the sum of all sides.
2. Write a C++ program that calculates gross pay. The program should read in the number of hours worked and the hourly rate. If the employee has worked more than forty hours then they should receive time and a half for everything over 40 hours. Print out the gross pay for the employee.
3. Write a C++ program that reads in three numbers and prints the largest of the three values.
4. Write a C++ program that computes a 6% tax on a sale when the amount of the sale is input by the user. The program should print the total tax and then the total amount of the sale (original amount + tax).

To submit the homework you need to include only the following in a compressed zip file:

1.A .cpp with the source code for question one.

2.A .cpp with the source code for question two.

3.A .cpp with the source code for question three.

4.A .cpp with the source code for question four.

5.One Microsoft word file that contains images of your programs running. Please see lab 1 for how to create the images.
