python的tkinter，能畫什麼圖？

今天從下午忙到如今，睡覺。

這個能繪點圖的。

import json
import tkinter as tk
from tkinter import filedialog
from tkinter import LabelFrame
from tkinter import StringVar
from PIL import Image, ImageTk


# 方塊大小
card_size = 120
# 繪圖起點座標
start_x = 400
start_y = 100
# 7 * 5 方格
x_grid = 7
y_grid = 5


# 打開文件，載入json文件
def open_file():
    fname = filedialog.askopenfilename(title='打開文件',
                                          filetypes=[('json', '*.json'),
                                                     ('All Files', '*')])
    # 更新Label text變量
    var.set(fname)
    with open(fname, 'r') as load_f:
        global card_dict
        card_dict = json.load(load_f)


# 繪圖
def draw_card():
    # 這個打開文件，用的是回調函數，我暫時也不知道如何不用這個全局變量
    global card_dict
    imgs_list = []
    for i in range(y_grid):
        y1 = start_y + i * card_size
        for j in range(x_grid):

            # 載入圖片
            img = Image.open(image_path)
            # 重定義大小
            img = img.resize((card_size, card_size), Image.BILINEAR)
            # 重定義旋轉
            img = img.rotate(image_num[2])

            imgs_list.append(imgs)
            # 每一次都全繪已有圖片
            for item in imgs_list:
                # 以nw左上角爲基準點
                cv.create_image((x1, y1), anchor='nw', image=item)
            # 不調用update，不會更新畫布
            win.update()
            # 停一秒再做下一步動做
            win.after(1000)
    # 不讓圖消失太快
    win.after(10000)


win = tk.Tk()

# 畫格子， 要算好橫縱座標
for i in range(y_grid):

cv.pack()
win.mainloop()

json文件格式：
