Data visualization Tutorials in Big Data Analytics
- In big data analyst, to analyse data, the concept lies in discovering insight than noting the plots for Data visualization
- To analyse data related to flights, begin the task by verifying whether there is any correlation among numeric values
- The source code is existing in the R file as follows bda/part1/data_visualization/data_visualization.R
The underlying example shows various ways to recognize data by using plots
- From the plots, it is clear that, there is vital correlation among variables in the dataset
- Delay in arrival and departure of flights are extremely correlated
- The illustration of ellipse is an example for linear relationship among variables
- It is not easy to discover cause through the result
- One variable may have an effect on an another
- From the plot, it is clear that there is correlation between distance and the time of air
- The flight time will increase as per the distance grows
- An effective way to visualize distributions are plotting in a box
- The source code is existing in the R file bda/part1/data_visualization/boxplots.R
- The underlying code shows the way to generate box plots & trellis charts through the library ggplot2
