Thank you for the suggestions! Unfortunately, none of the suggested libraries worked the way I wanted to, so I made a custom column chart library for this task on my own in html, css and javascript.

I think just yesterday I have recommended this opensource webapp for another question but it fits the bill perfectly for your usecase (that is if I have understood it correctly): DeckDeckGo This is an authoring tool and not only does it allow all the usual animation and stuff it has this very cool feature for polls which might be useful in a classroom ...

There is now a super-fast library for real-time data monitoring, and interactivity during data acquisition, LightningChart JS. It's made with WebGL, using GPU primitives to render the charts and graphs. The real-time performance is in totally different level than with other JavaScript charts. It works in web, mobile and desktop, a true cross-platform ...

These features are supported in LightningChart JS. See this code example.

LightningChart JS allows building charting dashboards with WebGL acceleration, and might be an overkill solution for your needs, eventually? It's super-fast, and low-cost, and free for personal use. For commercial use we ask small fee.

LightningChart JS works in Android, IOS and all operating systems with WebView or equivalent host control. It's free for personal use.

LightningChart JS has RectangleSeries, which is made for these kind of custom stacking of bars, and even custom width for each.

LightningChart JS meets these requirements, and it's free for personal use. It's not open-source though, but with WebGL GPU acceleration and extreme optimization, the performance is the best in the industry.

LightningChart JS has bitmap export with .saveToFile method, so it allows you to add the pic in IMG tag. The chart also can be run in server-side with Node.js, and it allows you to write a solution to export images for non-JS-enabled clients.

I feel Ant Design have enough nav and menu components to get this job done!

Give a try to https://c3js.org/ c3.js based on d3.js and can easily be customize and implemented.

I suggest taking a look at the Open Source Plotly JavaScript library it is very flexible and powerful and includes stacked bar charts. An example from the online documentation: var trace1 = { x: ['giraffes', 'orangutans', 'monkeys'], y: [20, 14, 23], name: 'SF Zoo', type: 'bar' }; var trace2 = { x: ['giraffes', 'orangutans', 'monkeys'], y: [12,...

I would recommend Syncfusion JS libraries. It has very good charts, gauges, maps, and more than 60+ other controls as well, and the best part is you can get it for free if you are an individual developer or if your company is generating less than 1 million in revenue. If you are eligible you can get the community license and try it out. Chart demos: https:/...

I recommend Cypress, which we use on a big project. Cypress builds on top of Mocha and adds a enough of convenience to allow all our QA engineers to write tests with little training needed. (Though we're adding one more layer of abstraction on top, because our bottleneck is the translation between test scenario documents and test code. Our project's ...

On Visual Studio, I think Resharper might be the best-in-class. Do some calculations, maybe it's worth its price for you. I'm using VSCode and there's good integrations for most big tools, like jest, mocha, chai, and more.
