Hover to Select: Interaction with Unidirectional Data Flow

Five fruit circles render in an SVG using D3 v5 within a React framework, with apples and lemons distinguished by ordinal color and radius scales. Hovering over a circle triggers a navy stroke via mouseover and mouseout events, updating a selectedFruit state variable that flows unidirectionally into the fruitBowl render function. Transitions animate circle entry, exit, and size changes over one-second durations as the fruit array is modified through pop and type replacement operations.

Bowl of fruit Hover to Select

Five fruit circles render in an SVG as apples and lemons; hovering one highlights it with a black stroke while the previous selection clears. The React and D3 v5 code uses a `scaleOrdinal` for color and radius, and enters, updates, and exits circles with a 1000-millisecond `transition`. The example demonstrates data joins by removing, changing, and filtering fruit items while animating circle size and position.

Hover to select

Five fruit circles of varying radius and color represent apples and a lemon, ordered in a row. Hovering over a circle triggers a `mouseover` event that calls `setSelectedFruit`, updating a black stroke on the active fruit, which clears on `mouseout`. Using d3 v5 with a module-based `fruitBowl` function, it binds data via `selection.data`, merges enter/update selections, and uses `scaleOrdinal` for mapping type to size and color. The SVG renders in a fixed 960×500 viewport, with dynamic updates as fruits are removed or replaced.

Five circles initially render as apples in a red-to-yellow color scale, with hover events highlighting the selected fruit via a black stroke. Using d3.v5 data joins and transitions, the example animates circle radius and position changes while updating the selection state through callbacks. Over sequential timeouts, the visualization removes fruits and mutates an apple into a lemon, demonstrating enter, update, and exit selections with d3.scaleOrdinal for color and radius values.

Fruit: Hover Gets Ya Selected

Five fruit circles sit in a row, each filled red for apples or yellow for lemons. Hovering over a circle selects it with a black outline, and hovering away deselects it. The visualization uses D3 v5 with SVG and animated transitions to smoothly change circle radius, position, and fill. The `fruitBowl` module maps fruit types to colors and sizes using `scaleOrdinal`, while `setSelectedFruit` updates the selection state on `mouseover` and `mouseout` events.

Bowl of Fruit - Hover to Select

This example presents a bowl of fruit as five circles, initially all apples, arranged in a row. Hovering over a fruit selects it, highlighted with a grey outline. The visualization uses D3 v5 with a data join to animate changes: fruits are removed after one and three seconds, and one apple transforms into a lemon after two seconds. The code leverages D3's `scaleOrdinal` for color and radius, React-like props for state, and SVG transitions for smooth animations.

Bowl of fruit - Hover to select

Five fruit circles are rendered in an SVG, initially all apples, with a black stroke appearing on whichever fruit the mouse hovers over. The code uses a React-style render function with d3 selections and the `scaleOrdinal` color and radius scales to map fruit types to visuals. Updates occur via timed transitions: an apple is removed, a lemon replaces one apple, and another apple is filtered out. The `fruitBowl` function handles enter, update, and exit selections with `.transition().duration(1000)` for animated changes, while mouseover triggers `setSelected` to update the selection state.

Bowl of Fruit - Hover to Select

Five pieces of fruit are rendered as color-coded circles in an SVG, with apples in red and lemons in yellow. Hovering over a circle highlights it with a black outline, and moving the mouse away removes the highlight. The visualization uses D3 v5's data join with key functions to smoothly transition circles entering, exiting, and updating, animating radius and position over one second. State changes, such as eating or replacing fruit, are triggered by timed events, with selection managed through React state and callbacks.
