Not for the same audience but for much the same idea I made a progressive visualization of saving and compound interest in a blog post about pension saving: https://calcwithdec.dev/posts/pictures-pensions/ I inten

People say that it's a practice. A few years ago I was determined to practice, and it was hard, and then it became easy, auto-relaxing, like a cheat. I lost that practice and now it's hard again. I think GP is right to question te

Thanks for the prompt! I made a new gallery that's mobile friendly and I almost forgot why I need to land it - adding it to the list!

If you need to know a leap year and it's before the year 6000, I made an interactive calculator and visualization [1]. It's >3 machine instructions (and I admire the mathematical tricks included in the post), but it does do tho

This is a cool way to teach! I was blown away by the little functions at first and I too made a clone to experiment with calculang [1]. I added an evaluation feature (F9) so you can select sub-expressions and see what they do, which was hel

Really pretty outputs! And impressive that the code is shown so elegantly and also interactive. This algorithm is one I use to demo some features in a language I'm making called calculang [0][1] I like the way you step through the logi

Post-retirement is definitely harder. There are also usually rules about what's allowable with the money that built up with tax relief and such. Since these rules differ from country to country even the starting point of deciding what

Author here - Health warning third bullet point is: > Even when there is tax relief to save for a pension, this doesn’t mean that there aren’t taxes on pension income after retirement and the footnote to it is: > often there are taxes

Hi - author here - these compound returns are not guaranteed. I reinforce this point under health warnings. Here the 6% compound returns is an assumption. If that's good or bad to use depends on the purpose of the projection. For long

To get my editor component and compiler interacting with that reactive system it got a little messy, and I'll review and hopefully fix it before I push this to a wider calculang playground. Hopefully it's my own bugs that I can fi

In this example it might not be so practical, but in calculang everything is a function including constants. This is because of an emphasis on flexibility. They're a constant here but in another calculang model I can call calculations

I use reactive Javascript which shows errors until a few pieces click together (best that I can understand it atm). So it's normal to have a string of errors and then everything works, but it should work in much less than 2s. I guess t

Thanks for checking it out and for the comment! This surprised me, but you are right. The only thing I can point to referring to this example only is that there is a lot of Javascript in the page, but the calculations are (effectively Javas

Hi! I made this scroll-based interaction to Visualize risk. The coordinated visuals are using Vega-Lite. The calculations are from composing calculang models: one which simulates returns, using one which calculates pension savings. I plan t

I like your conviction Re "functional programming is very easy to grasp". Many won't but I agree in the purest (sorry) sense. There is no scattered changing state. I think we all learned input-function-output as a construct i

One that I'm watching is the Table mark in Graphic Walker [1]. There is a license thing about logos to note if you do use it in Pretzel [2]. On GW [1], Create Dataset -> Public Datasets -> Student Performance then change the Mark

Looks great and thanks for sharing! You mentioned that you went to some length to implement pivots. How far do you think you will take the pivot feature and UI? For financial type usecases it's pretty much a requirement to be able to m
