Hello! I'd like to add [`GraphRecipes.jl`](https://github.com/JuliaPlots/GraphRecipes.jl) and [`GraphMakie.jl`](https://github.com/JuliaPlots/GraphMakie.jl) to the plotting section of the docs. I think it is also about time to remove links to [`GraphLayout.jl`](https://github.com/IainNZ/GraphLayout.jl) (archived, last update...

Hey! Thanks for providing this package, the only true way to compile latex documents :) Recently I've discovered a weird problem. I am not entirely sure whether this has anything...

This came up in [discourse](https://discourse.julialang.org/t/diffeq-savingcallback-save-befor-and-after-other-callback/59263): If some callback introduces new saving points in the solution object before and after the affect (`save_positions=(true,true)`) the `SavingCallback` should also save at both positions...

In CairoMakie `0.8.13`, the line ends plottet by `linesegments` look differently depending on whether `linewidth` is given as a vector or not. ```julia segs = Point2f.([(0, 0), (0,1), (1,0), (1,1)])...

MWE ```julia import Pkg; Pkg.activate(temp=true); Pkg.add("Symbolics") @variables t a(t) b(t) c(t) d(t) term1 = a - c - d |> Symbolics.unwrap term2 = substitute(a - b, b=>c + d) |>...

I use `solve_for` to rearange simple linear equations. This behaviour caught me off guard: ```julia @variables x y Symbolics.solve_for(x ~ x + y, x) ``` gives ```julia (-1//0)*y ``` Formally,...

Simplification of `x(t)/p` where `x(t)` is a variable does not change the term but removes metadata from `x(t)`. ```julia import Pkg; Pkg.activate(temp=true); Pkg.add("ModelingToolkit") using ModelingToolkit @parameters t p @variables x(t)...

This is a rework of #52. I changed the interface in the folloing way: - `initialpos` optionally allows for dictionarys now. So you can use something like `Dict(3 => (1,2,3))`...

take derivative of rhs and replace differential states i am not totally sure about the implications of that
