I want to achieve this kind of result but do you give me a clue how can I do it with less effort in react?
sliders
You can render SVG on the background.
I use functions for building a cubic bezier curves from this article.

Quite new with d3 but have been stuck on this for several weeks and figured I'd ask here
I've been trying to create a radial/flare tree using React-Flow but I'm having a really hard time with positioning the nodes. I need to use React-Flow because I'd like to use custom React components instead of the standard SVG nodes from d3 since I need a higher fidelity interaction with the nodes.
Essentially I'm looking for something like this attached image but using React-Flow:
Source: https://observablehq.com/#d3/radial-tree
I don't even need the radial curve lines- it's more of a nice to have. As long as I can get the nodes in the correct circular position, even straight lines are fine.
Would love any advice :)
Here's what I've got so far:
https://codesandbox.io/s/trusting-leavitt-b8uxi9-rf-expand-collapse-forked-fh71v8?file=/src/App.tsx:948-954
It's the collapsible tree example that the React-Flow devs gave on their website
The closest example of a radial tree using d3 using v4 or above is this: https://medium.com/analytics-vidhya/creating-a-radial-tree-using-d3-js-for-javascript-be943e23b74e
I'm trying to apply the logic that the author used in their example but the nodes aren't positioning correctly, probably due to my shallow understanding of how to use d3
There are a few other examples on here/codepen that creates a radial tree using d3 but they're all v3 or below and are focused around using SVGs as the nodes
I've also seen other radial trees from other React libraries like this: https://codesandbox.io/s/ov2jokvl1z
But they all use SVG nodes which won't work for me because I'd like to use React nodes within the graph
I am using Cesium to display a strictly 2D map in the browser (wrapped in React using the Resium library).
I am interested in giving the user the option to draw lines\polygons, and to measure the distances between two points or the area withing the polygon.
Basially, I want precisely this OpenLayeres example, but in Cesium: https://openlayers.org/en/latest/examples/measure.html
How would one go about doing it?
Thank you
I was doing some research on cesium drawing tool library.
It wasn't same as the one you asked but you can use it for your need. you can use for 2D and 3D maps. it gives all basic functionalities like draw circle, polygon, add marker, draw line, calculate distance etc.
I have found cesium-draw the library for the VUE.
[cesium draw ](https://www.npmjs.com/package/cesium-draw)<br>
If you can work with Angular their is a lot of cesium sport in angular so you can use
[angular-cesium](https://angular-cesium.com/)
if you have found any thing else please do share I love to see.
Hello to All react Native developers!
I am new to React Native.
and i didn't know how to create a square Progress-Bar.
Is there any way to create a square Progress-Bar with transparent background in React Native?
my requirement is that, i want to create a progress-Bar around a QR Code, and you already know that the QR Code is Square.
Please! Any one help me.......
I think what you're going to want is to wrap the QR code with 2 separate layered Views and fill in the top layered one similar to the standard methods for circular progress bars using whatever your progress metric is to define the radius of the fill.

Here is the actual shape I want to draw using maybe view style properties or are there any alternatives, thanks
Depending on your needs I would choose something like react-native-canvas they have pretty much everything you gonna need to draw.
Other option would be GCanvas.
With those options you will be able to draw free forms as you wish
But there`s always the option to use SVG as well.
In my past experiences SVG forms solved most of the cases, but sometimes I had to use this canvas libs to draw some more complex or dynamic forms.
Hope this can be of any help to you.
I really want to create circular slider. I've been searching, but I can't find any information. So any tutorial, guide or if someone already created like this. Please post their XML code.
Instead of making a circular slider (which as #auburg points out) would be a little unintutive to use (think the old telephone dials), consider making it a dial like a thermostat:
It's functionally very similar, but has a much larger hit-test area and is therefore less easy to mess-up for the user.
Try this guide: https://blogs.msdn.microsoft.com/jerrynixon/2012/12/06/walkthrough-building-a-sweet-dial-in-xaml-for-windows-8/
A circular slider can be implemented just like a normal horizontal or vertical slider. The only difference would be that in the MouseMove event handler of the thumb during the drag operation you cannot just handle the horizontal or vertical position. Instead you have to calculate the angle relative to the center of the slider and map that to the value of the slider.
