The steps for generating synthetic data for Analysis of Programming Languages Usage in a Software Development Environment are:

Step-1: Install the Python packages NumPy, Pandas, and Faker, laying the foundation for data manipulation and analysis in our project.

# Install required packages
!pip install numpy pandas faker

Step-2: Import the previously installed Python packages NumPy, pandas & faker.

# Import necessary libraries
import numpy as np
import pandas as pd
from faker import Faker

Step-3: Initialize faker for generating synthetic data

# Set up Faker for random data generation
fake = Faker()

Step-4: Declare the value of number of records/dataset, seeding value and also declare the necessary column names, their data types, value ranges and what ever the value are required.

# Generate synthetic dataset with multiple attributes
np.random.seed(42)
num_records = 1000

data = {
    'ProgrammingLanguage': [fake.random_element(elements=('Python', 'Java', 'C++', 'JavaScript')) for _ in range(num_records)],
    'YearsOfExperience': np.random.randint(1, 10, size=num_records),
    'ActiveDevelopers': np.random.randint(50, 500, size=num_records),

sns.boxplot(x='ProgrammingLanguage', y='VersatilityScore', data=df)
plt.title('Boxplot of Versatility Score by Programming Language')
plt.xlabel('Programming Language')
plt.ylabel('Versatility Score')
plt.show()

The box plot shows that Python has the highest median versatility score, followed by JavaScript and then Java. C++ has the lowest median versatility score. The box also shows that the distribution of versatility scores is relatively tight for Python and JavaScript, while the distribution is more spread out for Java and C++. This means that there is less variation in versatility scores for Python and JavaScript programs, while there is more variation for Java and C++ programs.

The whiskers of the box plot show the extent of the distribution of the data. The whiskers for Python and JavaScript extend to lower values than the whiskers for Java and C++. This means that there are a few Python and JavaScript programs with very low versatility scores, but most Python and JavaScript programs have relatively high versatility scores. In contrast, there are a few Java and C++ programs with very high versatility scores, but most Java and C++ programs have relatively low versatility scores.

Overall, the box plot shows that Python is the most versatile programming language, followed by JavaScript and then Java. C++ is the least versatile programming language. The box plot also shows that there is less variation in versatility scores for Python and JavaScript programs than there is for Java and C++ programs.

Pair-plot

A pair plot is a visualization technique that showcases pairwise relationships between multiple numerical variables in a dataset. By presenting scatter plots for each pair of variables and histograms along the diagonal, pair plots offer a holistic view of correlations and distributions. In our programming language analysis, pair plots serve as a comprehensive tool to explore connections among selected numerical attributes.

The pair plot is applied to visualize relationships between 'YearsOfExperience,' 'ActiveDevelopers,' 'VersatilityScore,' 'WeeklyDownloads,' and 'CommunitySupportScore.' By examining scatter plots and histograms simultaneously, the pair plot enables us to identify patterns, understand correlations, and gain a nuanced understanding of the complex dynamics within the dataset.

sns.pairplot(df[selected_numerical_variables])
plt.suptitle('Pair Plot of Selected Numerical Variables', y=1.02)
plt.show()

The pairplot shows the relationships between six numerical variables for a dataset of apps: YearsOfExperience, ActiveDevelopers, VersatilityScore, WeeklyDownloads, CommunitySupportScore, and AdditionalMetric1. Each variable is plotted against every other variable, creating a matrix of scatter plots.

The diagonal plots show the distribution of each variable. The distribution of YearsOfExperience appears to be right-skewed, with more apps having fewer years of experience. The distribution of ActiveDevelopers is also right-skewed, with more apps having fewer active developers. The distributions of WeeklyDownloads and CommunitySupportScore are more evenly distributed.

The off-diagonal plots show the relationships between the variables. There is a weak positive correlation between YearsOfExperience and VersatilityScore. This means that apps with higher versatility scores tend to have more years of experience, but the relationship is not very strong. There is also a weak positive correlation between ActiveDevelopers and VersatilityScore. This means that apps with higher versatility scores tend to have more active developers, but again, the relationship is not very strong. There is a weak negative correlation between YearsOfExperience and CommunitySupportScore. This means that apps with more years of experience tend to have lower community support scores, but the relationship is not very strong.

Overall, the pairplot does not show any strong relationships between the variables. This suggests that these variables may not be very good predictors of an app's success. However, it is important to note that this is just a small sample of apps, and the relationships between these variables may be different for a larger population of apps.

Bar-chart

Bar charts, using rectangular bars to represent categorical data, are a fundamental visualization tool. Each bar's length corresponds to the quantity it represents, making them ideal for summarizing information.
