This scatterplot displays the Local Outlier Factor (LOF) values from a CSV dataset, with each point’s opacity reflecting its anomaly score. The visualization uses React with D3’s `scaleLinear` for axes and `.ticks()` for grid lines, rendering points as SVG circles. Hovering reveals a tooltip showing the exact LOF value. The project imports data asynchronously via D3’s `csv` method and manually sets fixed x- and y-axis domains rather than computing extents.

AI-generated description

The data shown here comes from ans.csv.

This visualization has tooltip function, so be sure to hover over each point ;)

The opacity of each point depends on it's LOF value, i.e. the higher LOF value is, the darker the point is, which means the more "outlier" this point is.

Test2 answer for Big Data Management Final Project

This scatterplot visualizes the results of a local outlier factor (LOF) analysis, with each point colored dark green and its opacity scaled by the LOF value—higher LOF points appear darker, indicating greater outlierness. Hovering over a point reveals a tooltip showing the exact LOF score. The visualization uses React with D3 v5 modules including `scaleLinear` for axes and `csv` for data loading from a GitHub-hosted CSV file. The example is built with SVG rendering and custom React components for axes and marks.

Outlier scatter matrix 03

This example displays an outlier scatter matrix of cardio data, highlighting relationships among numeric attributes with a dense grid of small multiples. A draggable viewport lets users pan across the rendered scatterplot, shifting an oversized SVG map containing a red circle to explore off-screen portions. The visualization is built with the Vega-Lite API and D3, using d3.csv to load the dataset. The viewport interaction is implemented by manually tracking mouse events with onmousedown, onmousemove, and onmouseup, adjusting the map’s absolute position within a clipped container.

question-3

This scatter plot visualizes a dataset, mapping one attribute to the x-axis and another to the y-axis, with each point’s color representing a species category. The visualization uses the D3 library (v6) to load CSV data via `d3.csv`, scales the axes with `d3.scaleLinear`, and renders the points as SVG circles. Additional data fields for sales cost and rating are mapped to the circle’s `rx` and `ry` attributes, though they are not visually apparent in the default rendering. Axis labels are added using SVG text elements.

task-3

This scatter plot visualizes the relationship between two numeric variables from a CSV file, with data points colored red or blue based on their group designation. The visualization uses D3.js v7 to load and parse the data, then applies linear scales for both axes. The code constructs an SVG graphic with labeled axes generated through `d3.axisBottom` and `d3.axisLeft`, while circles with a radius of 5 pixels are placed using the `d3.scaleLinear` mappings to represent each data point.

Fork of Scatter Plot(test_data)

This fork of a scatter plot displays how a data point’s value changes over time, with a black line connecting sequential points overlaid on teal circles. It uses React to render an SVG, with axes and marks built from custom components. The code leverages d3.scaleLinear for scaling, d3.extent for domains, d3.format for tick labels, and d3.csv to load data from a remote testData.csv. The chart includes axis labels for “Time” and “Value,” and each circle shows a tooltip on hover.

Loading Data with React & D3

This example demonstrates loading and visualizing a CSV dataset of bike availability from a GitHub-hosted file in a React application. It shows a scatterplot of randomly positioned circles, where each circle represents the total number of bikes available for a given hour, with the radius scaled by the summed value. The code uses React hooks (`useState`, `useEffect`) to fetch the data with D3’s `csv` method and `d3.rollups` to aggregate the dataset by date-hour. The circles are rendered as SVG elements, with random opacity and positions, displaying the processed data directly.

Activity6_Question3

This scatter plot visualizes city data, mapping population on the x-axis against area on the y-axis, with each point colored by region using a categorical color scale. The code loads a CSV file from GitHub, parses it, and renders circles in an SVG using D3 v6 APIs such as `csv`, `scaleLinear`, `scaleOrdinal`, `axisLeft`, `axisBottom`, and `entries`. A legend, built with appended rectangles and text, identifies the region colors. The visualization uses the browser’s full window dimensions and positions axes with margin conventions.

Fork of React & D3 Starter

This scatter plot visualizes the relationship between student study hours and exam marks, with a summary showing total students and averages. It uses D3 v7’s `d3.csv` to load data, `scaleLinear` for axes, and `d3.axisBottom`/`axisLeft` for the coordinate system. The React wrapper (index.jsx) renders an SVG, while the standalone HTML version draws semitransparent steelblue circles for each student. Data comes from a raw GitHub CSV file hosted by the author, and the chart includes axis labels for hours and marks.
