Enhance the clarity of the images generated in the Code block interactive mode of the qmd document in VS Code

Scene description

I need to write document using Quarto in VS Code. There are Python code blocks in this document. When I run this code block in interactive mode, I find that the images rendered by jupyter are rather blurry. The following code needs to be added to the python code block to make it clearer:

```{python}
%matplotlib inline
%config InlineBackend.figure_format = 'svg'
```

My test code

---
title: "Just a test"
format: html
jupyter: python3
kernel: .venv
---

# No measures have been taken

```{python}
#| label: fig-polar
#| fig-cap: "A line plot on a polar axis"

import numpy as np
import matplotlib.pyplot as plt

r = np.arange(0, 2, 0.01)
theta = 2 * np.pi * r
fig, ax = plt.subplots(
  subplot_kw = {'projection': 'polar'} 
)
ax.plot(theta, r)
ax.set_rticks([0.5, 1, 1.5, 2])
ax.grid(True)
plt.show()
```

# Enhance display effect

```{python}
#| label: fig-polar2
#| fig-cap: "A line plot on a polar axis"

import numpy as np
import matplotlib.pyplot as plt

%matplotlib inline
%config InlineBackend.figure_format = 'svg'

r = np.arange(0, 2, 0.01)
theta = 2 * np.pi * r
fig, ax = plt.subplots(
  subplot_kw = {'projection': 'polar'} 
)
ax.plot(theta, r)
ax.set_rticks([0.5, 1, 1.5, 2])
ax.grid(True)
plt.show()
```

The rendering results of the above two code blocks through the interactive mode are shown in the following figure:

Demand description

• Like jupyter, qmd should not give question prompts. This is very annoying.

• Parameter Settings in the code block make the entire setting more concise and elegant, for example:

  ```{python}
  #| fig-backend: 'svg'
  code
  ```

We can't add that comment in general because it sometimes generates SVGs that are too large that end up breaking tools that process the result. This has specifically come up before and has caused user confusion, and so the omission is intentional. You're, of course, welcome to use it if you know it's safe in your case.

By default, svg is not enabled. Only the customized svg displayed by the user is enabled. Would this be better? Shall we consider removing the jupyter dependency？

What? Sorry, but "removing the jupyter dependency" makes no sense. Thanks for the feedback but our example is good as it is.
