加载R包

代码语言:javascript复制
library(tidyverse)
library(ggbeeswarm)
library(packcircles)
library(ggtext)
library(ggrepel)
library(camcorder)

导入数据

代码语言:javascript复制
df <- read_csv('data.csv')

数据清洗

代码语言:javascript复制
cent_bee <- df %>% group_by(gender) %>% arrange(-age) %>% 
  mutate(g_rank = row_number(), name = fct_reorder(name, age)) %>% ungroup()

绘制一个基础图

代码语言:javascript复制
p <- ggplot(cent_bee)   
  geom_beeswarm(aes(age, "group"), groupOnX = FALSE)  
  theme_minimal()  
  theme(plot.background = element_rect(fill = "grey99", color = NA))

# 构建ggplot图形,将结果存储在pp变量中
pp <- ggplot_build(p)

# 从pp对象中提取数据,并创建一个新的数据框pp_df
# 包含x, y坐标,半径r,以及cent_bee数据框中的其他相关列
pp_df <- data.frame(
  x = pp$data[[1]]$x, 
  y = pp$data[[1]]$y,
  r = 0.03,
  place = cent_bee$place_of_death_or_residence,
  gender = cent_bee$gender,
  name = cent_bee$name,
  age = cent_bee$age,
  still_alive = cent_bee$still_alive,
  g_rank = cent_bee$g_rank
) %>% 
  arrange(x) %>%  # 根据x坐标排序
  mutate(id = row_number())  # 为每行添加一个唯一的id

调整点的位置

代码语言:javascript复制
# 使用circleRepelLayout函数调整点的位置,以避免重叠
pp_repel <- circleRepelLayout(pp_df, wrap = FALSE, sizetype = "area")
# 使用circleLayoutVertices函数获取调整后的点的坐标
pp_repel_out <- circleLayoutVertices(pp_repel$layout)

数据整合

代码语言:javascript复制
pp_plot <- pp_repel_out %>% 
  left_join(pp_df, by = "id") %>% 
  mutate(x = x.x,y = y.x,color = case_when(place == "United States" ~ "#3B9AB2",
                                           place == "Japan" ~ "#78B7C5",TRUE ~ "grey20"),
    color2 = if_else(still_alive == "alive", color, colorspace::lighten(color, 0.8))) %>% 
  select(-x.x,-y.x,-x.y,-y.y) %>% select(x,y,color,color2,id,gender)

数据可视化

代码语言:javascript复制
ggplot(pp_plot)  
  annotate("text", x = c(110.3, 113.3), y = c(8, 4.5), label = c("Men", "Women"),hjust = 1, size = 6,color="black")  
  geom_polygon(aes(x, y   3.5 * as.numeric(factor(gender)), group = id, fill = color2))  
  geom_polygon(aes(x, y   3.5 * as.numeric(factor(gender)), group = id, color = alpha(color, 0.6)), fill = NA, linewidth = 0.5)  
  scale_x_continuous(breaks = seq(110, 124, 2), limits = c(110, 124))  
  scale_color_identity()  
  scale_fill_identity()  
  coord_fixed()  
  theme_minimal()  
  theme(legend.position = "none",plot.background = element_blank(),
    axis.title = element_blank(),
    axis.text.y = element_blank(),
    axis.text.x = element_text(color="black",size=8),
    panel.grid.major.y = element_blank(),
    panel.grid.minor.y = element_blank(),
    plot.margin = margin(10, 0, 10, 0))
