I thought it could be nice to show some examples rendered
with Sympy.
With unicode:
pprint(Integral(sqrt((1+x)/(x**2+3)),x)+Sum(1/j**2,(j,1,n)))
n
____
? ?
? ________ ? 1
? ? x + 1 ? ??
? ? ?????? dx + ? 2
? ? 2 ? j
? ?? x + 3 ?
? ????
j = 1
With ascii:
pprint(Integral(sqrt((1+x)/(x**2+3)),x)+Sum(1/j**2,(j,1,n)), use_unicode=False)
n
/ ____
| \ `
| ________ \ 1
| / x + 1 \ --
| / ------ dx + / 2
| / 2 / j
| \/ x + 3 /___,
| j = 1
/
By comparison, the LaTeX text could be
\int{\sqrt{\frac{x+1}{x^2+3}}dx+\sum_{j=1}^n\frac{1}{j^2}
which I don't have a problem reading it, but... for non-LaTeX users...
Finally, an example of a graphic:
plot(sin(x),(x,-2*pi,2*pi))
0.99830 | ... ...
| / \ / \
| / . / .
| . .
| . .
| . .
| . .
| . .
0.05872 | -------------.--------------------------.--------------
| . . . . /
| . .
| . .
| . .
| . .
| . .
| . / . /
| \ / \ /
-0.9983 | ... ...
-6.28319 0 6.28319
In this case we seem to get the same result with ascii and unicode,
or maybe Sympy does not distinguish for plotting, although both
pprint(plot(sin(x),(x,-2*pi,2*pi)),use_unicode=False)
and
pprint(plot(sin(x),(x,-2*pi,2*pi)))
seem to be accepted by Sympy.
Is this enough for math & data? What do you think?
Wow! These look amazing on the terminal. I am not quote-replying as I don't want to mess with the beautiful monospace rendering. I would love to read a maths/science/CS related blog that uses this kind of rendering. This is so pleasant to look at on both a terminal and a GUI client. I hope someone will take the time to write either a latex-to-gemtext compiler that can generate this, or a server that does it dynamically. -- Leo

I agree. To fluxion, I would remind you that the text/gemini format is meant to be served as Unicode by default, so if you were to simply stick those result graphics in a preformatted (```) block, they should look great in any gemini client. Thanks for the examples with Sympy. Very inspiring indeed!

Probably very badly. Which is why I'm somewhat critical of using fixed
format blocks for ASCII art.

Here?s how I would do it:
```An equation of two terms. They?re added together. The first term is an
integral with respect to dx. It?s of the square root of a single fraction.
The numerator of the fraction is x plus 1. The denominator of the fraction
is x squared plus 3. The second term is a summation. It starts at j equals
1 and goes to n. It sums up 1 divided by j squared.
n
____
? ?
? ________ ? 1
? ? x + 1 ? ??
? ? ?????? dx + ? 2
? ? 2 ? j
? ?? x + 3 ?
? ????
j = 1
```
It?s been a long time since I?ve heard anyone talk college-level math
aloud and you _definitely_ shouldn?t trust how I read the first term
aloud, but this is roughly how I?d put it on my capsule.

Sometimes we are blind to the most simple and nice way of doing something. Thanks!
