数据可视化：从饼图到扇形图的多种实现

1. 纽约时报风格可视化

纽约时报的可视化作品常结合饼图、条形图和信息文本，为可视化增添更多背景信息，便于解读。以下代码可生成基本的可视化结构：

data2 = read.table("service.csv", header = TRUE, sep = ",")
army = as.matrix(data2[1,2:16])
navy = as.matrix(data2[2,2:16])
airforce = as.matrix(data2[3,2:16])
marine = as.matrix(data2[4,2:16])
j = layout(matrix(c(1,2,2,2,1,3,4,5),2,4, byrow = TRUE))
layout.show(j)
barplot(army, names.arg= c(2000:2014), space = 0.5, main = "Army")
pie(pct, radius = 1, init.angle = 90, clockwise = TRUE, labels =labels, border = "white", col= c("#6C6D5D","#BEBCB0","#BEBCB0","#BEBCB0"))
barplot(navy, names.arg= c(2000:2014), space = 0.5, main = "Navy")
barplot(airforce, names.arg= c(2000:2014), space = 0.5, main = "Air Force")
barplot(marine, names.arg= c(2000
