# Quick start
* Render an animation: [3b1b:SquareToCircle](https://3b1b.github.io/manim/getting_started/quickstart.html#add-animations)
```python
from manimlib import *
from manim_express import GlEagerScene
scene = GlEagerScene()
circle = Circle()
circle.set_fill(BLUE, opacity=0.5)
circle.set_stroke(BLUE_E, width=4)
square = Square()
scene.show_creation(square)
scene.play(ReplacementTransform(square, circle))
scene.hold_on()
```
Operating graphics:
* hold down the `d` key or `mouse left` on the keyboard and move the mouse to change the three-dimensional perspective.
* hold down the `s` key or `mouse right` on the keyboard and move the mouse to pan the screen
* hold down the `z` or `ctrl` on the keyboard while scrolling the middle mouse button to zoom the screen
* scroll the middle mouse button to move the screen up and down
* reset camera view by pressing `r`
* close the window and exit the program by pressing `q` or `tab`
* pause the animation by pressing `space` or `ctrl` or `alt`
* previews animation clip by pressing `LEFT`
* next animation clip: `RIGHT`
* replay current animation clip: `DOWN`
* `manim_express` vs `Matplotlib`:
**Eager mode usage**:
```python
from manimlib import *
from manim_express import GlEagerScene
CONFIG.use_online_tex = True # If you don't have installed latex locally.
theta = np.linspace(0, 2*np.pi, 200)
x = np.cos(theta)
y = np.sin(theta)
scene = GlEagerScene()
scene.plot(x, y, color=GREEN, width=2, scale_ratio=1)
scene.show_plot()
scene.hold_on()
```
**Object oriented usage**:
```python
from manimlib import *
from manim_express import GlEagerScene
import numpy as np
class ScatterExample(GlEagerScene):
def clip_1(self):
n_features = 2
X = np.random.normal(0, 20, (2000, n_features))
theta = np.linspace(0, np.pi*2, 150)
r = 50
x, y = r*np.cos(theta), r*np.sin(theta)
self.scatter2d(X[:, 0], X[:, 1], size=.03, color=YELLOW, ratio=0.618)
self.scatter2d(x, y, size=.03, color=BLUE)
ScatterExample().render()
```
