circle | statistics ASCII circle for analysing byte entropy in files | Analytics library

In d3, we may change the order of elements in a selection, for example by using raise.

Yet, when we rebind the data and use join, this order is discarded.

This does not happen when we use "the old way" of binding data, using enter and merge.

See following fiddle where you can click a circle (for example the blue one) to bring it to front. When you click "redraw", the circles go back to their original z-ordering when using join, but not when using enter and merge.

Can I achive that the circles keep their z-ordering and still use join?

I have a simple on-hover CSS animation which makes slide transition between images.

When the user makes the hover on SECTION ONE and before the animation ends make hover on SECTION two, animation restart and make lagging move.

MY CODE:

I need to create circles in canvas using fabric. Every click, there is a circle created. However, if the new circle created it will replace old circle. This my stackblitz demo.

I borrowed the R code from the link and produced the following graph:

Using the same idea, I tried with my data as follows:

I am working on a simple whiteboard application where the drawings are represented by quadratic Bezier curves (using the JavaScript's CanvasPath.quadraticCurveTo function). I am trying to implement functionality so that an eraser tool or a selection tool are able to determine if they are touching a drawing.

To show what I'm talking about, in the following image is a red drawing and I need to be able to determine that the black rectangles and black point overlap with the area of the drawing. For debugging purposes I have added blue circles which are control points of the curve and the green line which is the same Bezier curve but with a much smaller width.

I have included my code which generates the Bezier curve:

I am building a Create a Recipe form using crispy forms and I am trying to use a datalist input field for users to enter their own ingredients, like 'Big Tomato' or select from GlobalIngredients already in the database like 'tomato' or 'chicken'. However, regardless of whether I enter a new ingredient or select a pre-existing one, I am getting the following error: "Select a valid choice. That choice is not one of the available choices.". How do I fix this error?

Visual:

models.py

To be able to see through to the other side what I want to do is make the circle area transparent so you are able to see through to the background image.

How would this be done?

Is there a way to do that?

This image is what I am trying to replicate in the code.

How do I make it transparent like that?

The snippet I provided currently looks like this:

I am trying to navigate to "/quiz" when Start Quiz button is clicked.

However when I compile my code I am getting the following error on the website application: [Home] is not a component. All component children of must be a or

I am new to react and if anyone can help me I would be grateful!

Here is my code for App.js:

After migrating my angular 6 project to 12. I am getting multiple warning in terminal
