My approach involves a zoomable, interactive interface. The plan is to visualize a wide range of objects, from the tiniest particles to the observable universe. It will be an engaging way to grasp these immense scales.\n\n\n**Refining the Object Data**\n\nI've been meticulously refining the data structure for the simulated objects. The initial focus is on ensuring a representative range, spanning from Planck lengths to the observable universe. My current priority is defining each object's size, name, description, and potentially an accompanying image. The goal is a balance between educational value and user engagement within the logarithmic zoom. I'm aiming for a compelling, interactive experience.\n\n\n**Implementing Zoom Functionality**\n\nI'm now fully immersed in the core logic. I've successfully set up the zoom functionality using a scale variable, allowing me to draw objects based on the zoom level. The data structure for various objects is ready. My current focus is on seamlessly handling user input for zooming, including mouse wheel and potentially slider and button controls. I'm also exploring a logarithmic scale to accurately represent the vast differences in object sizes.\n\n\n**Fleshing Out the Object Data**\n\nI'm now populating the `objectsData` array with more detailed information. I'm focusing on a diverse range, from the Planck length up to the observable universe, including Quark/Electron, Proton/Neutron, and the Solar System. I'm prioritizing accuracy for 2025 values, but abstract representations will serve for now. Adding size in meters is crucial for correct scaling and logarithmic zooming. My focus is on a solid foundation.\n\n\n**Defining Object Visuals**\n\nI'm currently focused on defining the initial visual representations for the `objectsData` elements. Instead of complex images for each scale, I plan to use simple shapes and labels. Specifically, a central circle or shape to represent the current focus, alongside text labels for other objects within a reasonable visible scale. I'll define these shapes' color and size based on `sizeMeters`, for better scaling. The plan is for simple, clear visual cues to aid the user's understanding, while maintaining performance.\n\n\n**Designing the Object Visuals**\n\nI've been mapping out the visual elements for each object, from the Planck length up to the observable universe. My current plan is for a central circle that represents the scale in focus. The size of this central circle and the text labels for the other objects will be calculated based on the zoom level, `scale`. I'm focusing on text labels to keep performance high and initial load times low. I'm prioritizing accuracy for values from 2025 where possible. The primary aim is creating a simple but informative interface.\n\nI'm starting to build a basic version. I'm focusing on simple shapes and labels. I'll represent the focus point with a central shape. I've settled on text labels for nearby objects. The size and color of these shapes will be based on object size and visibility at the current zoom level, as it's adjusted. Accuracy remains a key focus. The goal is to provide a clean and intuitive experience.\n\n\n**Developing the Drawing Logic**\n\nI'm making progress on the drawing logic for different objects. I'm focusing on calculating their sizes and positions based on the zoom level. My plan is to start with simple shapes and labels. I'm prioritizing the `draw()` function, iterating through the `objectsData` and rendering elements on the canvas. I'm using `sizeMeters` and the current scale to determine the shapes' visual size and location. My goal is a visually clear and informative display that scales correctly.\n\n**Designing the Core Zoom Logic**\n\nI've been concentrating on the fundamental zoom mechanics, developing the `scale` variable's logic. My goal is for a logarithmic system where `currentLogScale` controls the `scale`, `metersPerPixel`. The `draw()` function's implementation is next. It will render objects based on their size and position at the current zoom level. A slider will replace the basic controls, making zooming more intuitive. I'm aiming for a straightforward yet efficient rendering process.\n\n\n**Finalizing Drawing and Info Display**\n\nI'm now fully immersed in developing the `draw()` function and the info panel updates. I've designed logic to calculate object sizes in pixels, based on `sizeMeters` and the current `currentLogScale`. The `draw()` function iterates through objects and displays them on the canvas. Alongside, the info panel updates dynamically, displaying the name, size, and description of the object at the current scale. I'm focusing on ensuring accuracy in size and positioning, while keeping the interface clear and intuitive.\n\n\n**Implementing Basic Drawing**\n\nI'm now integrating basic drawing logic. I'll focus on getting the canvas rendering the most essential components, like the main zoomable object representation and labels. I've built the initial data structures needed for the `objectsData` array. It's time to build the `draw()` and `zoom` functionality. I'm prioritizing accuracy for a good initial experience.\n\n\n**Initializing the Core Structure**\n\nI'm making progress on the foundational code, setting up the `index.html`, `styles.css`, and the basic `main.js`. This foundational setup includes the canvas, zoom controls (slider and buttons), and an info panel. I'm focusing on responsiveness and laying out the components. The core logic for zooming will be next.\n\n**Implementing Basic Rendering**\n\nI've got the canvas, controls, and info panel all wired up. The `objectsData` is loaded. Currently, I'm defining the initial drawing function and event listeners for the slider and buttons. With the foundational structure in place, I'm ready to begin rendering objects and implementing zoom functionality, focusing on accurate scale representation.\n\n\n**Zooming in on Drawing Logic**\n\nI'm now integrating basic drawing logic. My focus is on the `draw()` function, making it iterate through the data array to render elements on the canvas. I'm calculating and using `metersPerPixel` to determine the object sizes and positions based on the `currentLogMetersPerPixel`. I'll start with simple shapes and labels. My goal is an accurate and easily-scalable display.\n\n\n**Initiating the Render Loop**\n\nI've finally set up the `draw()` and `updateInfo()` functions, readying them for the core render logic. The drawing process will iterate through the data, calculating object size in pixels. I am aiming for accurate scaling and information display. I am focusing on seamless transitions between scales.\n\n\nI've started building the drawing logic and the zoom functionality, focusing on accurate scaling, from Planck lengths to the observable universe. I'm leveraging logarithmic scaling for precision and a clear user interface.

I'm also now updating the info panel alongside the objects' visual representation. The current focus is ensuring accurate data representation and providing smooth UI interactions.\n\n\n**Updating the Drawing Logic**\n\nI'm currently focusing on the updated drawing logic, primarily in the `draw()` function, for proper object positioning and visibility. The updated drawing logic now works in tandem with zoom and `metersPerPixel`, making sure everything is drawn and updated at the correct size and location. The current efforts ensure the user has the best experience.\n\n\n**Updating Simulation Logic**\n\nI've been refining the logic for object positioning and labeling, specifically in the `draw()` and `drawUniverse()` functions. I'm focusing on ensuring accurate scaling based on `currentLogMetersPerPixel`. My primary focus is on refining the `objectSizePixels` calculation within the loop and centering objects on the canvas for a clean display. The plan is to enhance the user's perception of accurate size representation and smooth zooming.\n\n\nI've been working on the basic structure for the scale simulation. I've set up the HTML with the canvas, zoom controls (slider and buttons), and an info panel. In CSS, I've implemented a responsive layout with a dark theme and some initial styling. The `main.js` file is prepared with canvas setup, object data, and zoom-related variables.
