This area chart visualizes the average car horsepower by year, using data from a car performance CSV loaded via `d3.csv`. The chart aggregates raw Horsepower values into yearly averages with `d3.rollup`, then renders a semi-transparent filled area, an overlaid blue line, and interactive circles. It uses `d3.area`, `d3.line`, and `d3.scaleLinear` within an SVG, with a custom mouseover tooltip. The axes are labeled "Year" and "Horsepower," and the visualization is built entirely with D3.js v7.

Kumar Danam - LINE CHART

A line chart displays average car horsepower per year, with an overlaid scatterplot of individual data points, each circle colored by car model. The average trend is shown as a blue line, while hovering over any point reveals a tooltip with the model, year, and horsepower. The visualization aggregates the CSV data using `d3.rollup` and computes the mean horsepower, then renders the SVG with `d3.line` for the average line and `d3.scaleOrdinal` for color mapping. Interactive tooltips are enabled through `d3.select` and mouse event handlers.

Kumar Danam pie chart

This pie chart visualizes the distribution of horsepower across car models from a CSV dataset loaded via `d3.csv`. Each slice is rendered using `d3.pie` and `d3.arc` in an SVG, with labels positioned along an outer arc. Hovering a slice triggers a tooltip showing the model, horsepower value, and percentage of total. A color-coded legend, built with `d3.scaleOrdinal` and the Tableau10 scheme, accompanies the chart.

Kumar Danam Reusable scatter plot

This example demonstrates a reusable scatter plot of car data from a CSV file, showing horsepower and miles per gallon. It renders SVG circles with axes and labels, with the visualization automatically alternating the x- and y-axis assignments every two seconds. The code uses d3.csv for data loading, d3.scaleLinear for scaling, d3.axisBottom and d3.axisLeft for axes, and the scatterPlot function pattern for reusability in D3 v6.

Kumar-Reusable-Scatter

This reusable scatter plot displays the relationship between horsepower and miles per gallon for ten car models, using orange-red circles positioned by linear scales. Built with d3.v7 and the reusable chart pattern, the module encapsulates configurable accessor functions, axis labels, dimensions, and color through chainable setters. The visualization loads car_performance.csv via d3.csv with d3.autoType, filters for valid numeric values, and renders an SVG with d3.axisBottom and d3.axisLeft, updating circles through the join pattern.

activity 7 task 2

This area chart visualizes the maximum horsepower for various car makes, with the x-axis ordered by make and the y-axis scaled linearly from zero. The chart loads CSV data from a GitHub repository using `d3.csv`, then renders a filled blue area via the `d3.area()` generator onto an SVG canvas. Axes are added with `d3.axisBottom` and `d3.axisLeft`, and labels for “Car Make” and “Horsepower” are positioned using SVG text elements. The visualization uses D3 v7 with a clean, responsive layout and subtle hover opacity effects.

A5-Line Chart

This line chart displays the average horsepower of cars over time, with each point representing the mean value for a given year. The data is loaded from a CSV file hosted on GitHub Gist using `d3.csv`. The visualization uses D3 v6's `scaleLinear` for both axes, applies a monotone curve to smooth the line, and renders the chart as an SVG. Axis labels and a title are added with standard D3 axis functions.

Fork of Area Chart ice-7

This area chart displays the relationship between horsepower and miles per gallon for a set of cars, with a filled green region showing how MPG decreases as horsepower increases. The visualization loads a CSV file from GitHub using `d3.csv`, converts the numeric fields, and sorts the data by horsepower. It uses `d3.scaleLinear` for both axes, `d3.area` to generate the filled path, and `d3.axisBottom` and `d3.axisLeft` to render the coordinate axes. The SVG output is styled with CSS for a clean presentation.

Activity7_Answer2

This visualization displays the average horsepower for different vehicle types using an area chart with a monotone curve. The SVG chart is rendered with D3.js v7, which loads CSV data from a GitHub repository via `d3.csv`. The code computes group averages through `d3.rollup` and `d3.mean`, then scales the x-axis with `d3.scalePoint` and the y-axis with `d3.scaleLinear`. The filled area path is generated with the `d3.area` API, and axes are added using `d3.axisBottom` and `d3.axisLeft`.
