Original



Objective

The taken Visualisation is used to see how big the market of apple company is. This is decided by comparing the apple capitalization with different Country GDP, other companies capitalization ,etc.

The visualisation chosen had the following three main issues:

• Visual Bombardment The circular representation is overlapping and which makes it a complex visualisation for understanding.

• Issues of perception The round region one over other creates certain issues of perception and makes it difficult to observe the exact capitalization of country/company.

• Comparison Most of the disc or circular region appears to be of same size and shape which makes it difficult to compare the one capitalization with the other.

library(dplyr) 
library(readxl)
library(ggplot2)
DATA<- read_excel("DATA assign 2.xlsx")


DATA$Value <- as.numeric(gsub('[$,]', '', DATA$Value))
DATA$Value<-DATA$Value/1000000000

p<-ggplot(data=DATA, aes(x=`Company/Country`, y=Value)) +
  geom_bar(stat="identity")+coord_flip();

p<-p+ coord_flip()+ ggtitle("APPLE MARKET") +

Reconstruction

The following plot fixes the main issues in the original.

Due to reconstruction visual Bombardment has been covered through which all the data are easily visiable and also can compare any capitalization with the apple capitalization.
