This area chart shows the average fuel efficiency (MPG) of cars over model years, separated into three regions: the USA, Europe, and Asia. Each region is represented by a semi-transparent filled area with a smooth curve, using a color scale and a legend to distinguish them. The visualization aggregates data from a CSV file using d3.groups and d3.mean, then renders the areas with d3.area, d3.curveCatmullRom, and d3.axisBottom/axisLeft for the axes.

Activity-6_3

This scatter plot visualizes the relationship between horsepower and fuel efficiency (MPG) for cars from the Auto MPG dataset, with each point colored by the vehicle's region of origin (USA, Europe, or Japan). Using D3 v7, the code loads CSV data via `d3.csv`, maps it with a custom parsing function, and renders points as SVG circles with `d3.scaleLinear` for both axes and `d3.scaleOrdinal` for region-based coloring. The visualization includes labeled axes, a legend, and a red title, all rendered as SVG elements.

Activity6_q3

This scatter plot visualizes the relationship between horsepower and miles per gallon (MPG) for vehicles in the Auto MPG dataset, with points colored by region of origin (USA, Europe, Japan). It uses d3.csv to load the data, d3.scaleLinear for positioning both axes, and d3.scaleOrdinal for categorical color mapping. The SVG rendering includes axis labels, a legend, and circles with opacity, all generated using D3 v7 selections and the axisBottom and axisLeft components.

Activity6_task3

This scatter plot visualizes the relationship between horsepower and fuel efficiency (MPG) for 49 car models, with each point colored by the car's region of origin—American, European, or Japanese. The visualization uses D3.js v7 to load data from a CSV file and render SVG circles, with an interactive tooltip that appears on hover to display detailed specifications. The chart employs d3.scaleLinear for both axes, d3.scaleOrdinal for coloring, and d3.axisBottom and d3.axisLeft for the labeled axes. Hovering triggers animated transitions that enlarge the selected point and show a formatted HTML tooltip.

Area chart

This area chart shows the average fuel efficiency (MPG) of cars by model year, using data from the auto-mpg.csv dataset. The code loads the CSV with d3.csv, filters out invalid entries, aggregates averages with d3.rollups, and renders a smooth, semi-transparent blue area using d3.area with curveMonotoneX. Axes are drawn with d3.axisBottom and d3.axisLeft, and the chart is built in SVG.

Activity_6 Question 3

This interactive scatter plot visualizes the relationship between horsepower and fuel efficiency (MPG) for cars, with each point colored by the vehicle’s region of origin (USA, Europe, Japan). The visualization uses D3.js v7 (d3.v7) to render SVG elements, including circles that respond to mouseover events by displaying a tooltip with the car’s name, horsepower, and MPG. Data is loaded from a remote GitHub CSV file using `d3.csv`, and scales are constructed with `d3.scaleLinear` and `d3.scaleOrdinal` to map the quantitative and categorical attributes, respectively.

Activity_6 Task3.2

This interactive scatter plot visualizes the relationship between car horsepower and fuel efficiency (MPG), with data points colored by the car's country of origin. Built using D3.js v7, the visualization loads CSV data from a GitHub repository and renders it as an SVG with smooth hover tooltips displaying detailed car information. A legend distinguishes between USA, Europe, and Japan vehicles. The implementation uses standard D3 APIs including `scaleLinear`, `scaleOrdinal`, `axisBottom`, `axisLeft`, and `csv`, applying a `transition` for animated tooltip effects.

Activity 6

This scatter plot visualizes the relationship between horsepower and miles per gallon (MPG) for cars, with points colored and shaped by origin (USA, Europe, Japan). The visualization uses d3.csv to load data from a GitHub-hosted CSV file and renders the chart as an SVG with d3.v7. Interactive tooltips appear on mouseenter to display car details, while a legend indicates the mapping between shape, color, and origin. The implementation uses d3.scaleOrdinal, d3.symbol, and d3.axisBottom/axisLeft to create the marks and scales.

Activitity6_Question3

This scatter plot visualizes the relationship between horsepower and miles per gallon (MPG) for a cars dataset, with each circle colored by the vehicle’s origin (USA, Europe, or Japan). The visualization uses D3 v6 to load CSV data via `d3.csv`, parse and filter the rows, and render SVG circles with linear scales for both axes. Axis labels and ticks are added using `axisLeft` and `axisBottom`, while the full window width and height define the chart area. The code explicitly filters out rows with missing or invalid numeric values before mapping the data points.
