實驗程序（附結果截圖）：
1.練習掌握pyecharts的安裝和使用方法
（1）打開Windows命令視窗，執行 “pip install pyecharts” 命令安裝pyecharts庫
（2）執行 “pip list” 命令查看安裝結果
（3）使用pyecharts制作柱狀圖
from pyecharts.charts import Bar
v1 = [70, 85, 95, 64]
str1 = ['數學', '物理', '化學', '英語']
bar1 = Bar()
bar1.add_xaxis(str1)
bar1.add_yaxis('成績', v1)
bar1.render()
2.練習使用pyecharts繪制柱狀圖、儀表盤圖、3D圖、雷達圖、面積圖等
（1）繪制柱狀圖
from pyecharts.charts import Bar
from pyecharts import options as opts
v1 = [70,85,95,64]
v2 = [80,75,85,70]
str1 = ['數學','物理','化學','英語']
bar = Bar()
bar.add_xaxis(str1)
bar.add_yaxis('小明', v1)
bar.add_yaxis('小紅', v2)
bar.set_global_opts(title_opts=opts.TitleOpts(title='柱狀圖', subtitle='分數'))
bar.render()
（2）繪制儀表盤圖
from pyecharts import options as opts
from pyecharts.charts import Gauge
c = (
Gauge()
.add("", [("完成率", 66.6)])
.set_global_opts(title_opts=opts.TitleOpts(title="Gauge-基本示例"))
.render("gauge_base.html")
)
（3）繪制3D圖
import pyecharts.options as opts
from pyecharts.charts import Bar3D
