数据准备

# 加载数据
data <- data.table::fread(jsonlite::read_json("https://hiplot.cn/ui/basic/circular-pie-chart/data.json")$exampleData$textarea[[1]])
data <- as.data.frame(data)

# 整理数据格式
data$draw_percent <- data[["values"]] / sum(data[["values"]]) * 100
data$draw_class <- 1
data2 <- data
data2[["values"]] <- 0
data2$draw_class <- 0
data <- rbind(data, data2)
filtered_data <- data[data[["values"]] > 0,]

# 查看数据
