As my title suggests, I am trying to create a bar chart using d3 in React to add data insights to a web app. I am overwhelmed by the countless tutorials that have yet to help me create a minimalist chart that simply provides 5 vertical bars that pass in props and nothing else.
Could somebody please recommend good online lessons to get me over the steep learning curve? This is my first time using d3, and it is my only option for frameworks since it is an in-house standard at my company.

I need a piece of advice. I want to create a React web application with React using typescript and I want when clicking a button to show a new page with a scene of a town. What is the best way to make it possible, I mean to integrate the scene in the React Project. I saw recently that I can use ReactVR to create a 3D scene. Is this the best way to do this or there is another way to do what I want. Please give me a piece of advice.
Thank you for reading this and for your interest.
I suggest to use a mixt between react-babylone and a simple canvas.
react-babylone support react hooks you will not found a problem with react versions .
There are a good community and you can find answers quickly in case of difficulty.

I actually recommend we go with Google's Model Viewer library as it is the easiest if you want to 3d viewing assets. there is some other's Three.js and Babylon.js as well

I am wanting to render a short piece of animation on the splash screen of my CN1 app but am struggling.
The Lottiefiles website contains a lot of good animation content, but the closest example i can find to using it is within XCode. I have the downloaded JSON file, of the animation, but am wanting to know if anyone has figured a way of incorporating into a CN1 Java app?
I can see that developers have used in Java, but CN1 wouldn't allow the LottieAnimationView component on it's layout manager i would guess.

Any pointers appreciated. Thanks
The "right way" would probably be to wrap the native implementations for the various OS's in a cn1lib so you can use lottie in a cross platform way. There's a long tutorial about wrapping native code in the developer guide and Steve did a 3 part video series on the subject a few years back: https://www.codenameone.com/blog/integrating-3rd-party-native-sdks-part-3.html
It's mostly mechanical so it shouldn't be too hard. If you want to take a shortcut you can probably use the web version of the API in a BrowserComponent and call it a day.
I have a sample data that I want to visualize by a graph like this in React Js:
And this is the link to the JavaScript code:
Burtin’s Antibiotics Protovis
Does anyone has any idea that which React graph library I can use for having exactly this?
Thanks in advance
The library that this example is taken from is deprecated:
Protovis is no longer under active development.
The final release of Protovis was v3.3.1 (4.7 MB). The Protovis team
is now developing a new visualization library, D3.js, with improved
support for animation and interaction. D3 builds on many of the
concepts in Protovis; for more details, please read the introduction
and browse the examples.
So you should continue your investigations into D3 and React. Here is an article about it: https://medium.com/turo-engineering/react-meets-d3-6a40881d0d73
When one talks about rendering charts or any kind of data
visualization in the web, D3.js is the de facto standard. So, if we
want to build beautiful and reusable charts, we should definitely
leverage the power of D3.
How do we integrate it? But we have a problem, our web client is built
in React and this library doesn’t get along well with D3: both use
very different approaches to update the DOM. While React uses a
virtual DOM and a well defined lifecycle to calculate and optimize DOM
updates, D3 uses the browser DOM and data attributes.
If we want to build nice charts, with neat animations and don’t have
our heads burst when dealing with SVG elements and their positioning,
using D3 is a must, so we need to find a way so these two libraries
can play well together.
I am well versed with server-side programming using .Net C# and front-end MVC and Angular. I have seen some state of the art websites where they have animations included in webpages. Since it seems like Flash might be on the verge of extinction I do not want to spend time to learn it. What other technologies are they using to add animations to websites? For example to add accessories to cars with animations. Thanks for your help.
You might be talking about WebGL, which is inserted into HTML5 with a canvas tag. It renders graphics with JavaScript but uses a web version of OpenGL.
You can simplify a lot of work with additional libraries for WebGL such as Three.js, p5.js and others. That way you don't have to work with shaders, and build models with individual vertices and polygons.
I am fairly new to React native, and I am looking for a good way to have a sortable list. To my knowledge, I was unable to find any good examples that I could replicate (though there is one repo being worked on). Without the HTML5 drag and drop, what is the basic strategy for drag and sort with React Native? Thank you.
React Native Sortable List
I tested out about 5 different solutions, none of which worked very well, especially on Android, so I invested a day of programming to update the most promising, which was React Native Sortable List.
Now it works fantastic on both iOS and on Android. Here's an animation of it in action on both platforms (click the image to watch the gif).
I also tested a lot of packages but they were all buggy and couldn't achieve what I wanted to do.
So I wrote my own sortable list (vertical and horizontal). Feel free to check it out and leave a comment. It's written in Javascript so it's compatible with any type of project.
Here is an example of it:
