解释这段代码: mtcars %>% as_tibble() %>% ggplot(aes(x = wt, y = mpg, shape = factor(vs), color = hp)) + geom_point(size = 3) + colorspace::scale_color_continuous_sequential(palette = "Dark Mint") + scale_shape_discrete(labels = c("V-shaped", "Straight")) + labs( x = "Weight (1000 lbs)", y = "Miles per gallon", title = "Motor Trend Car Road Tests", shape = "Engine", color = "Horsepower" ) + theme( text = element_text(size = 18, color = "white"), rect = element_rect(fill = "black"), panel.background = element_rect(fill = "black"), legend.key = element_rect(fill = "black"), axis.text = element_text(color = "white"), plot.title.position = "plot", plot.margin = margin(10, 10, 10, 10) ) + guides( shape = guide_legend(override.aes = list(color = "white")) )

treemapify::deciduous_tree:在ggplot2中绘制树图
这段代码是使用 R 语言中的 ggplot2 包绘制一个散点图,其中 x 轴表示汽车重量,y 轴表示每加仑油能行驶的英里数,shape 表示汽车引擎类型(V 形或直列),color 表示汽车马力,使用的调色板为 Dark Mint。代码中使用了管道操作符 `%>%`,将数据框 mtcars 转换为 tibble 类型后再进行绘图操作。另外,还对图形进行了一些美化设置,包括标题、图例、背景颜色、坐标轴颜色、字体大小等。最后还覆盖了图例颜色为白色。
