1. 使用GeoCodeStudio库
```python
from geocodestudio import *
初始化画布
canvas = Canvas(width=800, height=800, background_color=(255, 255, 255))
定义圆形参数
circle_center_x, circle_center_y = 400, 400 圆心坐标
circle_radius = 200 半径
绘制圆形
canvas.draw_circle(circle_center_x, circle_center_y, circle_radius, color=(255, 0, 0)) 红色圆形
显示画布
canvas.show()
```
2. 使用HTML与SVG
```html
