Types of Plots

  an overview of different types of plots commonly used in data visualization, including line plots, bar plots, scatter plots, box plots, and histograms. Let's summarize the characteristics and appropriate use cases for each type of plot:

  1. Line Plot (Line Chart):

    • Characteristics: Displays data as a series of data points connected by straight lines.
    • Use Cases: Captures trends and changes over time, compares datasets with a continuous independent variable, illustrates cause and effect relationships, and visualizes continuous data.
    • Best Practices: Ensure accurate scaling on axes to reflect data accurately.

  2. Bar Plot (Bar Chart):

    • Characteristics: Displays data using rectangular bars where the height or length represents the magnitude of the data.
    • Use Cases: Ideal for comparing different categories or groups, excel with discrete data, show contributions to the whole, and visualize rankings.
    • Best Practices: Choose appropriate axis scales to avoid misleading plots.

  3. Scatter Plot:

    • Characteristics: Presents values for two variables using Cartesian coordinates, with data points displayed as a collection of points.
    • Use Cases: Examines relationships between two continuous variables, detects outliers or unusual observations, identifies clusters or groups, and explores complex data.
    • Best Practices: Handle outliers properly to enhance accuracy and meaningful insights.

  4. Box Plot (Box and Whisker Plot):

    • Characteristics: Displays the distribution of a data set along with key statistical measures using a box, whiskers, and outliers.
    • Use Cases: Compares the distribution of a continuous variable across different categories or groups, visualizes quartiles and outliers, and compares distributions of multiple variables.
    • Best Practices: Pay attention to outliers and their impact on data interpretation.

  5. Histogram:

    • Characteristics: Graphical representation of the distribution of a data set, showing the frequency or relative frequency of values within specific intervals using bars.
    • Use Cases: Provides insights into data distribution, outliers, skewness, and variability, visually depicts the shape of the data, and showcases data variability.
    • Best Practices: Carefully choose binning options to avoid oversimplification or overcomplication of the distribution.

In summary, each type of plot has its own characteristics and is suited for specific use cases in data visualization. By understanding the strengths and limitations of each plot type and following best practices, we can effectively communicate insights and findings from our data.

Common cybersecurity terminology

  As you’ve learned, cybersecurity (also known as security) is the practice of ensuring confidentiality, integrity, and availability of information by protecting networks, devices, people, and data from unauthorized access or criminal exploitation. In this reading, you’ll be introduced to some key terms used in the cybersecurity profession. Then, you’ll be provided with a resource that’s useful for staying informed about changes to cybersecurity terminology. Key cybersecurity terms and concepts There are many terms and concepts that are important for security professionals to know. Being familiar with them can help you better identify the threats that can harm organizations and people alike. A security analyst or cybersecurity analyst focuses on monitoring networks for breaches. They also help develop strategies to secure an organization and research information technology (IT) security trends to remain alert and informed about potential threats. Additionally, an analyst work...
