This example demonstrates the “Hello World” of a VizHub V3 Runtime Environment, showing a blank SVG canvas that fills the container’s width and height. The code uses D3’s `select` and `selectAll` with a data join of `[1]` to create an empty SVG element. The visualization highlights a minimal setup for continuous hot reloading with interactive widgets, serving as a template for building more complex charts. The entry point is the exported `main` function, which receives the `container` DIV as its argument, and the example lacks an `index.html` file, triggering the V3 Runtime.

AI-generated description

A blank slate starting point showing the "Hello World" for the VizHub V3 Runtime Environment, which supports continuous hot reloading with interactive widgets.

  • There is no index.html - that's what triggers the V3 Runtime
  • The entry point is the main function exported from index.js
  • The main function takes an argument container, a DIV

This example demonstrates the fundamental structure of a VizHub V3 visualization, starting from a blank canvas. It shows how the `main` function receives a DIV container and uses it as the mounting point for all visual output. The code implements a simple circular shape using basic SVG elements within the container, serving as a minimal "Hello World" for the runtime environment. The example highlights the V3 Runtime's continuous hot-reloading capability, where changes to the code instantly update the rendered visualization. It uses plain JavaScript and SVG APIs, with no external libraries, to establish the baseline for subsequent tutorials.

Circles with D3

This example demonstrates a blank D3.js starter using the VizHub 3 runtime. It renders a single SVG element that adapts to the container’s dimensions. The code relies on the D3 `select` API and the `.join('svg')` method to create or update the SVG, with explicit width and height attributes. The visualization does not display any data or additional graphics beyond the empty SVG canvas.

This example demonstrates the VizHub V3 Runtime Environment's interactive widget system. The code exports a `main` function that takes a `container` DIV element and sets its inner HTML to display a “Hello World!” message. Users can hold the Alt key and drag the numeric `fontSize` variable within the editor to continuously hot-reload the text at varying sizes. The example serves as a minimal starting point for building more complex interactive data visualizations within this framework.

Circles with D3

This example demonstrates the basic structure of a VizHub V3 visualization using a gray SVG canvas populated with six colored circles. It shows how to establish an SVG scene and render data-driven shapes, with each circle’s position, size, and color specified by properties in a JavaScript array. The code uses the D3 library, specifically the `select` API, to create the SVG container and join circle elements to the data, setting attributes like `cx`, `cy`, `r`, and `fill`, along with a fixed opacity value.

Circles with D#

This example demonstrates a minimal interactive runtime environment where a large, resizable text element displays "Hello World!" centered within a container. The visualization shows how the text size remains fixed while the container dimensions can change, highlighting the dynamic layout behavior. The code uses the `main` function exported from `index.js`, which receives the container element and sets its inner HTML with inline styles. No external data or rendering libraries are used; instead, it relies on plain DOM manipulation to showcase the core pattern for building data visualizations in the VizHub V3 Runtime.

circle_1

This example showcases a simple "Hello World" visualization in the VizHub V3 Runtime Environment, demonstrating the platform's interactive coding capabilities. The main function writes a text element into a container div, with font size controlled by an interactive widget that responds to Alt-drag gestures for live property adjustments. The code uses plain HTML and JavaScript, with the container's clientWidth and clientHeight providing measurable dimensions for layout. It serves as a foundational template for building more complex interactive visualizations.

This example shows a blank slate starting point for the VizHub V3 runtime, displaying a single fixed circle on an SVG canvas. The code uses `d3.select` and `selectAll` with a data join to create an SVG element sized to the container's dimensions, then binds a one-element dataset to render a circle at coordinates (316, 231) with a radius of 86. The static visualization demonstrates the minimal setup required for the runtime, which supports hot reloading and interactive widget adjustments.
