This D3.js v7 bubble chart visualizes the relationship between GDP per capita, life expectancy, and population for countries in 2007, with bubbles positioned by GDP (on a log scale) and life expectancy, while bubble size encodes population. The chart uses `d3.scaleLog`, `d3.scaleSqrt`, and `d3.scaleOrdinal` to map data attributes, and renders in SVG with hover tooltips built via `d3.select` and the `.join` operator. Data is loaded from a CSV file containing country-level indicators, and the visualization includes legends for bubble size and continent color coding.

Activity6_Question 4

This D3.js bubble chart visualizes the correlation between GDP per capita, life expectancy, and population for 25 countries. The x-axis represents GDP in USD, the y-axis shows life expectancy in years, while bubble size encodes population in millions, and color distinguishes each country. The visualization uses `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` for color assignment, and `d3.axisBottom` and `d3.axisLeft` for tick marks. Interactive tooltips appear on mouseover, displaying detailed country data, implemented with SVG `circle` elements and HTML div overlays. A legend with sample circles and labels explains the population scale.

Activity-6_Question-4.9

This D3.js bubble chart plots 50 countries by GDP per capita on the x‑axis and life expectancy on the y‑axis. Each circle’s area is proportional to population, and color encodes geographic region. Hovering highlights a bubble and shows a tooltip with exact country statistics. The visualization uses `d3.scaleLinear` for axes, `d3.scaleSqrt` for bubble radius, `d3.scaleOrdinal` with `d3.schemeCategory10` for colors, and SVG for rendering.

Activity6_Task4_Qus4

This bubble chart visualizes the correlation between GDP per capita, population, and life expectancy across ten countries using D3 v7’s `d3.csv`, `d3.scaleLinear`, and `d3.scaleOrdinal` APIs. Bubbles are positioned by GDP (x-axis) and life expectancy (y-axis), with radius encoding population and color assigned per country. Animated SVG circles support interactive tooltips on mouseover and mouseleave events, revealing detailed numeric values for each nation. The visualization reads from the included `countries.csv` dataset and renders entirely in the browser via SVG.

Activity-6_Question4

This bubble chart shows the correlation between GDP per capita, life expectancy, and population area ratio across 20 countries. Each circle’s position encodes GDP and life expectancy, while its size represents population density, with color distinguishing nations. A tooltip reveals exact values on hover. Built with D3 v7, it uses `d3.scaleLinear` for axes and bubble sizing, `d3.scaleOrdinal` with `d3.schemeCategory10` for colors, and SVG circles with mouse event handlers for interactivity. Data comes from `bubblechart.csv`, rendered with standard SVG elements and a categorical legend.

Activity6_Task4

This bubble chart shows the relationship between GDP per capita, life expectancy, and population for ten countries, with circle size encoding population and position encoding the economic and health metrics. The visualization uses D3.js v7 with SVG rendering, employing d3.scaleLinear for the x and y axes and d3.scaleSqrt for the radius scale. Data from countries_data.csv is loaded via d3.csv. Hovering over a bubble increases its opacity, while country labels appear inside each circle. Axis labels for GDP and life expectancy are added using d3.axisBottom and d3.axisLeft.

Activity_6_Q9

This bubble chart visualizes the relationship between population, GDP, and life expectancy for 15 countries, with each country represented by a colored circle. The x-axis shows GDP in USD, the y-axis shows population, and bubble size encodes life expectancy. Built with D3 v7, the visualization uses `d3.scaleLinear` for axes and bubble sizing, `d3.scaleOrdinal` with `d3.schemeCategory10` for colors, and includes interactive tooltips on mouseover. SVG circles are rendered with animation-ready styling, and a legend illustrates life expectancy values.

Activity-6_Question-4

This bubble chart visualizes the correlation between GDP per capita, life expectancy, and population area ratio across 20 countries. Each circle’s position encodes GDP per capita on the x-axis and life expectancy on the y-axis, while its size reflects population density. The code uses d3.csv to load data, d3.scaleLinear for axes and bubble sizing, and d3.scaleOrdinal with schemeCategory10 for country colors. Interactive tooltips appear on mouseover, and a legend is built with SVG circles and text labels.

Activity6_Task4

This visualization shows the relationship between GDP per capita, life expectancy, and population for ten countries. Each bubble’s x and y positions represent GDP and life expectancy, while the bubble radius encodes population size, with a categorical color scale distinguishing countries. Using D3 v7, the code loads data from a CSV file, scales values with `d3.scaleLinear`, renders SVG circles, and adds interactive tooltips that display country-specific details on mouseover. Axis labels and a title clarify the chart’s context, and the animation of tooltip transitions enhances user exploration.
