This example shows five circles positioned according to x and y coordinates loaded from a local CSV file. Clicking a circle highlights it by changing its fill to white with a black stroke. The React app uses a custom hook with ResizeObserver to track container dimensions, then renders the visualization with D3 v7's selection and scaleLinear APIs. Data loading uses d3.csv to fetch and parse numeric values, and circle interactions update React state to trigger re-renders.

Fork of CV: Loading CSV Data

This example shows five circles positioned on a responsive full-screen SVG, with data loaded from a CSV file containing id and x/y coordinates. Clicking a circle toggles its fill from black to white, adding a black outline to indicate selection. The React app uses a custom hook with ResizeObserver to track container dimensions, then passes d3-selection and d3-scaleLinear to render circles with scaled positions. D3’s csv function parses the data, and the circle selection is managed through React state, triggering re-renders via useEffect.

Fork of CV: Loading CSV Data

This example demonstrates loading CSV data in a React application and rendering interactive circles in an SVG. It uses d3.csv to fetch data.csv, mapping string values to numbers for the id, x, and y fields. The d3.scaleLinear function scales the x and y coordinates to fit the container’s dimensions, which are tracked via a ResizeObserver. The circles are redrawn with d3’s join method, responding to click events by toggling a selected circle’s fill color between white and black, managed through React state.

Fork of CV: Loading CSV Data

This example shows how to load and visualize a small CSV dataset as interactive circles in an SVG. The chart displays five data points positioned by their x and y coordinates, with clickable circles that highlight the selected point. Built with React and D3 v7, the App component uses d3.csv to parse the data, scales it with d3.scaleLinear, and renders the visualization through d3.select and selection.join. A custom useContainerDimensions hook tracks the container size via ResizeObserver, enabling responsive scaling of the fixed-domain coordinates.

Fork of CV: Loading CSV Data

This example demonstrates an interactive scatter plot of five data points loaded from a CSV file, rendered as circles scaled to the container size. Clicking a circle selects it, turning its fill from black to white with a black stroke. The code uses React with hooks for state management and container dimensions, while D3 v7 handles CSV parsing via `d3.csv` and SVG rendering through `select`, `join`, and `scaleLinear` for positional mapping.

Fork of CV: Loading CSV Data

Five circles read from a CSV file form a static scatter plot over a responsive full-viewport container. Clicking a circle toggles its selection state, highlighting it with a white fill and black stroke. The React app loads the data with `d3.csv`, manages container dimensions using a `ResizeObserver` hook, and renders the SVG circles via `d3.select` and `d3.scaleLinear`.

CV: Loading CSV Data

This example demonstrates how to load and visualize data from a CSV file using React and D3 v7. It renders five circles positioned according to x and y coordinates read from `data.csv`, with interactive click-to-select behavior that highlights the chosen circle. A custom `useContainerDimensions` hook tracks the container size using `ResizeObserver`, while D3's `csv` function parses the data and `scaleLinear` maps data coordinates to screen space. The `join` method efficiently handles circle creation, updating, and removal in the SVG rendering.

Assignment 5

This example shows five circles positioned by x/y coordinates from a small CSV dataset, with black fill by default and white fill with a thick black stroke for the currently selected circle. The React app loads data via d3.csv, tracks selection state, and resizes the SVG through a ResizeObserver in a custom hook. Rendering uses D3 v7 selections with scaleLinear to map coordinates to container dimensions, and click handlers trigger the selection callback.
