It's really funny because when building something, I will often look at overall cost as one of the main motivators for doing something for a personal business.
Another tool some might find useful, which I was introduced to during YC Startup School:
Startup growth calculator that helps get a basic feel for funding requirements and runway length. Really helps when it's visualized like that.
I made this four years ago as an experiment in D3 when the scroll-to-transition style was first getting popular (think nytimes and such).
All of it is basically hand-rolled D3 transitions with lots of debugging around enter/exit state... haven't looked at D3 lately so not sure if it's any easier. Charting libraries are a dime a dozen now, but these days when I need some easy charting, I like the D3+React bindings from VictoryCharts https://formidable.com/open-source/victory/docs/victory-char...
Kinda hard to wrap your head around how they do transitions in react-eese, but well, so is raw D3...
Quick suggestion: You mention "Venture Makr" at the end but dont provide any way to capture my email and no way to be notified of Venture Makr's launch.
