Project 1: Movie Correlation Project

This project was done on Jupyter Notebook, mainly based on Python. In this project, I've found some correlations between different fields of the given dataset.

• Data was taken from the movie dataset.
• The dataset: movies.csv.zip
• The project is mainly based on pandas(for data cleaning), numpy(for statistics), seaborn and matplotlib(for data visualization).
• Some of the visualizations from the project:

Project 2: Survey on Masculinity in the USA

This is the first project I did for my portfolio, where I built dashboards using a masculinity dataset.

• Data was taken from the masculinitysurvey dataset.
• The dataset: Masculinity survey.zip
• Cleaned dataset: Cleaned_masculinity_dataset.csv, mainly this dataset was used.
• A portion of Cleaned dataset was used while building the project.
• This is how my dashboards look like:

Do check it out!

Project 3: London Bike Rides

This project consists of well-organised dashboard where I tried to visualize the avg. moving rides in London in different climatic conditions such as Temperature, Windspeed and weather.

• Total Rides between the selected range where dashboard automatically detect the min. and max. range for months and display visualization accordingly.
• Tried to pullout the use of "Tooltips" with finese so that whenever you hover over the timeline graph, you'll see two nice and clean barcharts for the selected range.
• Applied clear filters, so just play with it and enjoy!!!
• Dataset: London Bike rides Dataset (From Kaggle)

Project 4: Major Project-Covid-19

You can download the required dataset from the following website-> https://ourworldindata.org/covid-deaths

File 1: Data Cleaning by python- covid-data-cleaning.ipynb

• In this file, I've dropped some unnecessary fields from the .csv file by using pandas.
• Divided the original dataset into two .csv files:

1. CovidDeaths.csv
2. CovidVaccinations.csv

You can find these datasets here- Divided covid datasets.zip.

Since I love python, I used Jupyter Notebook here. You can directly execute this step using MS-Excel.

File 2: Data Cleaning by MySQL- COVID PORTFOLIO PROJECT.sql

• Performed some basic operations and functions so that data can be easily explored and visualized by Tableau.
• Extracted 4 sub .csv files

1. Table1_GlobalNumbers.csv,
2. Table2_DeathsInContinent.csv,
3. Table3_HighestInfectionRateComparedPopulation.csv and
4. Table4_HighestInfectionRateComparedPopulationpt2.csv

File 3: Covid Dashboard.tbwx

• By using the 4 csv files extracted by SQL, I've visualized them on a single dashboard. Explore and play around with it. Thank you!
• Glimpse to that dashboard->

Project 5: Data cleaning using MySQL- Nashville Housing Data

• Dataset: Nashville Housing Data for Data Cleaning.xlsx.zip
• Cleaned this dataset by using MySQL.
• Used CTE's.
• Atlast, deleted unused columns in the given dataset.

Project 6: Washington House Sales

The aim for this project is to find out the Daily avg. House Sales in King County, Washington between the May 2014 and May 2015. I have tried to categorize the house as per the views such as excellent, good, fair, etc. and conditions such as Fair-Badly worn, poor-worn out etc. with the help filters, in different zip codes.

• Dataset:- HouseData.xlsx
• Developed a Tableau dashboard to visualize Daily avg. House sales at specific zip codes.
• Distributed the house price, Bedrooms and Bathrooms using histograms followed by their views and conditions heatmap filtered by yr built, sqft. living and a nice calendar.
