This example visualizes a polynomial function as a series of fixed-size red circles plotted across a green background. The circles are positioned by evaluating the polynomial y = x² + 3x + 2 at negative increments between -10 and 10, then scaling both coordinates to fit the container dimensions. Using D3 v7, the code selects and joins circle elements via `select().selectAll().data().join()`, applying `cx`, `cy`, `r`, `fill`, and `opacity` attributes. The rendering is computed directly from polynomial constants rather than external data.

Fork of Circles with D3

This example plots polynomial functions as a series of red circles. The visualization calculates y-values for a given set of polynomial constants across a range from -10 to 10, then scales the resulting points to fit the screen dimensions. Using D3 v7’s `select` API and the `.join()` operation for efficient SVG element creation, each circle is positioned and rendered with a fixed radius and 70% opacity. By modifying the `polynomial_constants` array or the `range_min`/`range_max` values in the code, different curves can be displayed.

This example displays a collection of colored circles of varying sizes and positions on a light blue background. The circles are arranged without a specific pattern, creating a chaotic, abstract composition. The visualization uses D3.js to render the SVG elements, with each circle's properties (center coordinates, radius, and fill color) specified in a hardcoded data array. The code employs D3's `select` and `join` API, setting the background, and applies a consistent opacity of 0.708 to all circles.

This example uses D3.js to render seven colored circles of varying sizes and positions on a dynamically sized SVG canvas. The visualization demonstrates the D3 data join pattern, binding an array of objects containing x, y, radius, and fill properties to circle elements with a uniform opacity. The code employs `select`, `join`, and `.attr` methods to create and style the shapes, showcasing method chaining and the General Update Pattern for dynamic SVG rendering.

A static visualization of seven circles in a cream-colored container uses a custom palette of muted colors like charcoal gray, burnt orange, and beige. The circles are connected by thin, semi-transparent lines, and larger ones are framed with rounded rectangles. Rendered with D3 v7, the code uses `select`, `join`, and attribute setters like `.attr` to draw geometric shapes from hard-coded data arrays, demonstrating basic SVG construction without animation or interaction.

This example demonstrates how to create a set of colored circles positioned dynamically within an SVG container using D3. The visualization binds an array of circle objects to SVG circle elements, specifying each circle's x and y coordinates, radius, fill color, and opacity. The code uses D3's `select`, `selectAll`, `data`, and `join` methods to manage the SVG and circle elements, with the container's dimensions determining the SVG's width and height. The data is hardcoded in the script, and the circles render with distinct vibrant colors against a light green background.

A data visualization displays seven overlapping green circles of varying sizes and positions on a light green background. The example uses D3 version 7 to bind an array of circle objects to the SVG. The `join('circle')` pattern creates and updates elements, setting positional attributes `cx`, `cy`, `r`, and `fill` with an opacity of 0.708. The code defines a `config.js` file with pencil color constants, though these are not referenced in the main rendering logic.

This example uses D3 to render a static collection of seven colored circles on an SVG canvas. The code employs the D3 General Update Pattern with `selectAll`, `data`, and `join` to bind an array of objects containing x, y, radius, and fill properties to circle elements. A light green background is applied via inline styles, and each circle uses a semi-transparent opacity value. The visualization demonstrates dynamic attribute assignment through arrow functions and method chaining within a `main` export function.

This example demonstrates how to draw a set of circles with D3.js, positioning them using explicit x and y coordinates and styling each with a distinct fill color and opacity. It shows the core data-join pattern by binding an array of circle objects to SVG elements, then using method chaining to set attributes like center position, radius, and color. The visualization uses the D3 `select` function and the `join` method to manage the SVG container and its children. The approach emphasizes a clean separation between data and rendering logic, making it easy to swap in different datasets or apply thematic modifications.
