Project Activities

All our Data Science projects include bite-sized activities to test your knowledge and practice in an environment with constant feedback.

All our activities include solutions with explanations on how they work and why we chose them.

Plot a line chart of COVID-19 New Cases in Denmark

In this activity, you will create a line chart to analyze the trend of new COVID-19 cases in Denmark over time. The x-axis will represent the Date_reported, and the y-axis will display the number of new cases. The goal is to visualize how the number of cases fluctuated throughout the reported period in the dataset.

  • Figure size : 10 by 6

  • Title : New COVID-19 Cases in Denmark

  • x-axis label: Date

  • y-axis label: New Cases

  • Line label: "New Cases"

Visualizing the Distribution of Countries Across WHO Regions

In this activity, you will create a pie chart using the region_counts series to display the distribution of countries across different WHO regions from the dataset. Use the following parameters to format your chart:

  • Figure size: 8 x 8

  • Title: WHO Regions Distribution

  • Percentage display (autopct): %1.1f%%

Finally, apply .tight_layout() and display the plot.

Visualizing the Distribution of Cumulative Deaths

Plot a histogram to visualize the distribution of cumulative deaths using the Cumulative_deaths column. Use the following parameters to format your histogram:

  • Figure size : 10 by 6

  • Title: Distribution of Cumulative Deaths

  • x-axis label: Cumulative Deaths

  • y-axis label: Frequency

  • Color: Red

  • Bins : 10

Apply .tight_layout() and display the plot.

Customized Line Plot of New COVID-19 Cases in Denmark

Redo the line plot of new COVID-19 cases in Denmark from the previous section using the series monthly_cases with the following customizations:

  • Figure size : 10 by 6

  • Line color: Green

  • Line style: --

  • Line width: 3

  • Title: New COVID-19 Cases in Denmark (Use font size 16 and set the font weight to bold)

  • x-axis : Date (Use font size 12)

  • y-axis labels: New Cases (Use font size 12)

  • x-axis rotation: Set the rotation of the x-axis labels to 45 degrees

Apply .tight_layout() and display your plot.

Customized Pie Chart of WHO Regions with EURO Slice Emphasized

In this task, you will create a pie chart to visualize the distribution of WHO regions, with a special emphasis on the EURO region by exploding its slice by a fraction of 0.1. Use the region_counts series and apply the following customizations:

  • Figure size : 8 by 8
  • Percentage display (autopct): %1.1f%%
  • Starting angle: 90 degrees
  • Colors: Defined in the notebook
  • Title formatting: Font size 16, bold font weight, and dark blue color for the title ("WHO Regions Distribution")
  • Explode the EURO slice to emphasize it

Additional settings:

  • Add a shadow effect
  • Ensure the pie chart is a perfect circle by setting the axis to equal
  • Use .tight_layout() for proper formatting and display the plot

Histogram with Custom Bin Size

In this task, you will create a histogram to visualize the distribution of cumulative deaths, with customized bin size and formatting. Follow the steps below:

Figure size : 12 by 7

Bins: Divide the data into 15 bins

Bar color: Red, with black outlines

Transparency: Set alpha to 0.7 for the bars

Title: "Distribution of Cumulative Deaths" (Font size: 18, Font weight: bold, Color: dark blue)

x-axis label: "Cumulative Deaths" (Font size: 14, Color: purple)

y-axis label: "Frequency" (Font size: 14, Color: green)

Grid: Add dashed lines (--) with linewidth=0.6 and alpha=0.8

Tick customization:

  • x-axis ticks: Adjust label size to 12 and set label rotation to 45 degrees
  • y-axis ticks: Set labelsize=12

Finally, use .tight_layout() to ensure proper formatting and display the plot.

Create an Unfit Pie Chart Using Time Series Data

In this activity, you'll use the Series daily_cases to create a pie chart, despite it being an inappropriate choice for this data type. The goal is to highlight the limitations of using a pie chart for time series data like daily COVID-19 cases. Use the following parameters to plot the chart:

  • Figure size : 8 by 8

  • Start angle: 90 degrees

  • Percentage display (autopct): %1.1f%%

  • Title: "New COVID-19 Cases Over Time"

Apply .tight_layout() and display the plot.

Visualize New COVID-19 Cases by WHO Region Using a Bar Chart

Using the region_cases Series, which records the number of new COVID-19 cases in each WHO (World Health Organization) region, construct a bar chart to present this data visually.

Figure size: 8 x 6

Title: New COVID-19 Cases by WHO Region

y-axis label: New Cases

Apply .tight_layout() and display the plot.

Generate Incorrect Scatter Plot of Cumulative Cases

In this activity, you will generate a scatter plot to visualize the cumulative COVID-19 cases for countries within the EMRO region using the DataFrame case.

Figure size: 10 x 6

x-axis : Country, fontsize=12

y-axis : Cumulative Cases, fontsize=12

Color : green

Title: Cumulative Cases in EMRO (Incorrect - Scatter Plot), fontsize = 16

Rotate the x-axis labels by 45 degrees for better readability and use .tight_layout() to display the plot

Why is it important to group your data or perform calculations on it before visualization?

Why is it inappropriate to use a bar plot to represent continuous time-series data like daily new COVID-19 cases?

Why is it more effective to use a heatmap rather than a bar chart when visualizing data like daily sales across different products and regions?

Create a Line Plot for New Cases and New Deaths with Custom Legends

In this activity, you will create a line plot to visualize both new COVID-19 cases and new deaths. You will work with the df_grouped DataFrame, which aggregates the daily new cases and deaths. . Follow the parameters outlined below:

Figure Size: 10 x 6

New cases

  • Color: Blue
  • Line Width: 2
  • Line Label: "New Cases"
  • x-axis Label: "Date Reported" (Font size: 12)
  • y-axis Label: "New Cases" (Color: Blue, Font size: 12)
  • x-ticks: Rotate by 45 degrees
  • y-ticks: Set label color to Blue

New Deaths

  • Color: Red
  • Line Width: 2
  • Line Label: "New Deaths"
  • y-axis Label: "New Deaths" (Font Color: Red, Font Size: 12)
  • y-ticks: Set label color to red.

Legend

  • Location: Upper left
  • Bounding Box Anchor: (0.1, 0.9) with bbox_transform=ax1.transAxes
  • Font Size: 12

Title - Text: "New COVID-19 Cases and Deaths Over Time (7-Day Rolling Average)" - Font Size: 16

Finally, apply .tight_layout() and display the plot.

Generate a Colormap Scatter Plot of New COVID-19 Cases

In this activity, you will create a visually engaging scatter plot to represent the trend of new COVID-19 cases over time, utilizing a colormap for better insight into the data. Use the scatter function to plot Date_reported on the x-axis and New_cases on the y-axis with the following parameters:

Figure size : 10 by 6

cmap : viridis

size : Set the size of the scatter points to 50.

alpha : 0.8 for slight transparency.

Colorbar Addition:

Include a colorbar to provide a reference for the color mapping, labeling it as "Number of New Cases" to clarify the representation of color intensity.

Title : "Scatter Plot of New COVID-19 Cases" with a font size of 16 to ensure visibility.

Label the x-axis as "Date Reported" and the y-axis as "New Cases," both with a font size of 12 for clarity.

Rotate the x-axis ticks by 45 degrees to improve readability of date labels, and use .tight_layout() to ensure all elements are displayed without overlap.
