Data Visualization on Old Cars Price Dataset

About Dataset:

An Indian dataset on Old Car Prices.
Data extracted from https://www.machinehack.com/course/predicting-the-costs-of-used-cars-hackathon-by-imarticus/
Original dataset: 'Data_Train.xlsx'
The dataset originally used on the wesbite has been cleaned by me, which is the one included in the project as 'car_clean.csv'
Cleaned Dataset has 6019 data points and 14 features.
The data_viz_slides.html is the final presentation consisting of tutorial.

Packages used:

Some common plots used:

Histograms
Bar graphs
Boxplots
Violin Plots
Barplots
Clustered Bar plots
Scatterplots
Heatmaps

Conclusions:

Univariate:

Top cities of old cars: Mumbai, Hyderabad, Kochi, Coimbatore. least Ahmedabad
Kilometers Driven is almost uniform distribution
Diesel and Petrol constitutes more than 80% of cars
Most cars are manual
Price of Car: first > Second > third > Fourth & Above
log of prices is normally ditributed. ie price is highly right skew
Top 4 cars: Maruti, Hyunday, Honda, toyota constitute more than 80% of cars

Bivariate:

Order of Mileage: CNG > LPG, Diesel > Petrol
Mileage of ELectric Vehicles are NaN
LPG has high variability
CNG is highly left skew
Highest average price of car in Coimbatore and lowest in Kolkata
Price has a direct correlation with Price
Electric and Diesel cars are expensive, while CNG and LPG are cheaper
Price of Automatic Cars is SIGNIFICANTLY high than Manual cars
Engine_CC and Price: slightly +ve correlation
Power_bhp and price: good +ve correlation
Power_bhp and Engine_CC: Highly =ve correlation
Kilometers Driven and Year: Good -ve correlation

Multivariate

LPG and CNG lie have lower Engine_CC and Power_bhp
Only Petrol cars lie in the higher Power_bhp and Engine_CC range
In Manual vs Automatic cars, the trend of Petrol, Electric and Disel car prices is completely reversed
