A stacked bar chart shows vehicle sales across five brands, with each bar divided into three color-coded car categories: SUV, sedan, and mini. The chart uses D3 v7's `d3.stack()` and `d3.scaleBand()` to position horizontal bars, with `d3.scaleLinear()` mapping the sales totals. Hovering over a segment triggers a tooltip displaying the exact sales value for that brand and category, using D3 event handlers for mouseover, mousemove, and mouseout interactions.

2_Question

This example visualizes car brand specifications as a stacked bar chart, where each bar represents a vehicle make and is divided into three colored segments for horsepower, torque, and highway MPG. The chart uses d3.stack() to compute stacked series from the CSV data, with d3.scaleBand positioning makes along the y-axis and d3.scaleLinear mapping values to the x-axis. Hovering over any segment triggers a tooltip displaying the specific spec type and value, while the chart includes axes with labels and a title rendered using SVG.

Question2

A stacked bar chart visualizes the distribution of horsepower, torque, and highway MPG metrics across 31 car makes, with each bar segmented to show the proportional contribution of each metric. The chart uses D3.js v7 with SVG rendering, employing `d3.stack()` to generate stacked series and `d3.scaleOrdinal` to assign colors. Hovering over a segment displays a tooltip showing the exact metric value formatted with `d3.format('.2f')`. The data comes from a CSV containing average specifications, with axes labeled "Value" and "Rating" for clarity.

Question2

A stacked bar chart displays quarterly sales by product category, with categories on the y-axis and sales totals on the x-axis. The visualization uses D3 v7's `d3.stack`, `scaleBand`, `scaleLinear`, and `scaleOrdinal` APIs to construct the chart, with tooltips revealing the category and sales amount per segment. Data from the CSV file is loaded and rendered as SVG rectangles, with an interactive legend and axis labels. The code leverages D3's declarative `.join` pattern for efficient element updates.

question 2 stacked bar chart

This stacked bar chart shows sales by product category (Clothing, Equipment, Accessories) across five store locations, with each bar segment proportional to category revenue. Built with D3 v7, it uses `d3.stack()` to process the CSV data and `d3.scaleBand` and `d3.scaleLinear` for the axes. The SVG rendering includes interactive tooltips on mouseover and a custom color scale using `d3.scaleOrdinal`. The dataset comes from an embedded CSV file, and the chart features labeled axes and a legend.

Activity6-Question-2.3

This stacked bar chart shows sales distribution across six product categories, broken into five rating ranges from less than 5 to greater than 8.5. The visualization uses D3 v7’s `d3.stack()` to create the layered bars and `d3.scaleBand`/`d3.scaleLinear` for axes. An interactive tooltip appears on mouseover via D3 event handlers, displaying the sales segment value. Data loads from a CSV file, with a custom color scale for each range and a legend rendered alongside the chart.

Activity-6 Q2

This stacked bar chart visualizes car sales distribution across five manufacturers, showing the percentage of cars sold in each price range (below 100, 100-200, 200-300, 300-400, above 400). Each horizontal bar represents a manufacturer, segmented into colored sections for each price bracket. Hovering over any segment displays a tooltip with the precise sales percentage. The visualization uses D3.js v7 with `d3.stack()`, `d3.scaleLinear()`, `d3.scaleBand()`, and `d3.scaleOrdinal()` to create the chart, which is rendered as SVG.

Question 2

A stacked bar chart visualizes sales performance by region, breaking down percentages across four product categories using data from a local CSV file. The chart employs D3 v7's `d3.stack` and `d3.scaleBand` to render SVG rectangles, with a tooltip triggered by mouse events. An ordinal color scale maps categories, and axes display percentage values. The static title and legend complete the presentation, showcasing local module imports alongside the D3 library.

Activity6_question2

This stacked horizontal bar chart displays sales totals for five store locations, broken down by product categories including clothing, equipment, and accessories. The visualization uses d3.stack() to compute the segmented bar series and d3.scaleLinear and d3.scaleBand for positioning. Rendered as SVG with D3 v7, the chart includes interactive tooltips that display precise numeric values when hovering over each segment. Category colors are assigned via d3.scaleOrdinal, and axis labels and legends are manually added.
