Here's a brief explanation of why the changes helped your graph display correctly:\n\n- **Expression Compilation:** By compiling the mathematical expression once with `math.compile(func.value())`, we create an object that can efficiently evaluate the expression multiple times, which is necessary for plotting the graph.\n\n- **Evaluation of Expression:** The `expr.evaluate(scope)` line evaluates the expression for each x value as it loops through the width of the canvas. This provides the corresponding y value for each x, which is essential for plotting the graph.\n\n- **Mapping Values:** The `map` function is used to convert the x and y values to canvas coordinates. This ensures that the graph fits within the canvas dimensions. For x values, we map from `0` to `width`, and for y values, we map from `-10` to `10` to `height` to `0`.\n\nThese changes allowed the graph to be plotted correctly on the canvas.

To enable zooming and moving (panning) on the graph, we need to modify the current setup and add some interaction features. Here's how you can implement these features:\n\n1. **Zooming:** We'll use mouse scrolling to zoom in and out.\n2. **Panning:** We'll use mouse dragging to move the graph around.\n\nLet's make these changes step-by-step:\n\n### Step 1: Add Variables for Zoom and Pan\n\nFirst, add global variables to store the zoom level and pan offset:\n\n```javascript\nlet zoomLevel = 1;\nlet panX = 0;\nlet panY = 0;\n```\n\n### Step 2: Update the `graph` Function\n\nModify the `graph` function to account for zoom and pan:\n\n```javascript\nfunction graph() {\n background(0);\n stroke(255);\n noFill();\n beginShape();\n const expr = math.compile(func.value());\n\n for (let x = 0; x < width; x++) {\n const scope = {\n x: map(x + panX, 0, width, -10 / zoomLevel, 10 / zoomLevel) // Adjust for zoom and pan\n };\n const y = expr.evaluate(scope);\n vertex(x, map(y, -10 / zoomLevel, 10 / zoomLevel, height + panY, 0 + panY)); // Adjust for zoom and pan\n }\n endShape();\n}\n```\n\n### Step 3: Handle Zooming with Mouse Wheel\n\nAdd a function to handle zooming:\n\n```javascript\nfunction mouseWheel(event) {\n zoomLevel *= (event.delta > 0) ? 0.9 : 1.1; // Zoom out with wheel down, zoom in with wheel up\n graph(); // Redraw the graph with new zoom level\n}\n```\n\n### Step 4: Handle Panning with Mouse Drag\n\nAdd functions to handle panning:\n\n```javascript\nlet isDragging = false;\nlet previousMouseX;\nlet previousMouseY;\n\nfunction mousePressed() {\n isDragging = true;\n previousMouseX = mouseX;\n previousMouseY = mouseY;\n}\n\nfunction mouseReleased() {\n isDragging = false;\n}\n\nfunction mouseDragged() {\n if (isDragging) {\n panX += (previousMouseX - mouseX) / zoomLevel;\n panY += (previousMouseY - mouseY) / zoomLevel;\n previousMouseX = mouseX;\n previousMouseY = mouseY;\n graph(); // Redraw the graph with new pan position\n }\n}\n```\n\n### Explanation\n\n- **Zoom Level:** Controls how much the graph is zoomed in or out. It modifies the range of x and y values.\n- **Pan Offset:** Adjusts the x and y position of the graph based on mouse dragging.\n- **Mouse Wheel Event:** Changes the zoom level using the mouse wheel.\n- **Mouse Drag:** Adjusts the pan offset to move the graph.\n\n### Final Step: Add Event Listeners in `setup`\n\nEnsure these events are set up in the `setup` function:\n\n```javascript\nfunction setup() {\n createCanvas(windowWidth, windowHeight);\n background(0);\n func = createInput();\n func.position(10, 10);\n button = createButton(\"Evaluate\");\n button.position(10, 50);\n button.mousePressed(graph);\n graph(); // Initial draw\n}\n```\n\nNow you should be able to zoom and pan your graph using the mouse!

Currently, the panning adjustments might not be consistent with the intended transformation.\n\nLet's refine the logic for panning in the `graph` function:\n\n### Update the `graph` Function\n\nHere’s how you can modify the `graph` function to correctly handle panning:\n\n```javascript\nfunction graph() {\n strokeWeight(5);\n noFill();\n beginShape();\n const expr = math.compile(func.value());\n\n for (let x = 0; x < width; x++) {\n // Calculate the scope for x including zoom and pan adjustments\n const scope = {\n x: map(x, 0, width, -width / 2 + panX / zoomLevel, width / 2 + panX / zoomLevel) / zoomLevel\n };\n const y = expr.evaluate(scope);\n\n // Map y-coordinate considering zoom and pan\n const yPos = map(y, -height / 2 + panY / zoomLevel, height / 2 + panY / zoomLevel, height, 0);\n \n vertex(x, yPos);\n }\n endShape();\n}\n```\n\n### Explanation\n\n- **Scope Calculation:** The `x` value is mapped from screen coordinates to graph coordinates, considering both `panX` and `zoomLevel`. This ensures that panning and zooming affects the horizontal positioning correctly.\n- **Y-Coordinate Mapping:** The `y` is evaluated and mapped back onto the screen, considering `panY` and `zoomLevel`. This ensures that vertical positioning is consistent with panning and zooming.\n- **Zoom and Pan Adjustments:** Both `x` and `y` calculations now correctly incorporate the effects of panning and zooming, preventing any unintended effects like parallax.\n\nThese changes should resolve the parallax effect and make the graph behave correctly when panning and zooming.
