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.

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_Ques4

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 (x-axis) and life expectancy (y-axis), while its radius represents population density. The visualization uses D3 v7 with SVG rendering and interactive tooltips that display country-specific values on hover. A categorical color scale distinguishes countries, paired with a legend. The chart reads data from a CSV file and animates tooltip transitions, with circle opacity increasing on mouseover for enhanced readability.

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.

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.

Question4_Bubble chart

This bubble chart visualizes the correlation between GDP per capita, life expectancy, and population-area ratio for 20 countries. Each circle’s position maps GDP and life expectancy, while its radius encodes population density, with color distinguishing nations. Data is loaded via `d3.csv` from `bubblechart.csv`. The visualization uses `d3.scaleLinear` for axes and size, `d3.scaleOrdinal` with `d3.schemeCategory10` for colors, and SVG circles with interactive tooltips on mouseover. A legend identifies each country.

Activity 8 - Q4.9

This bubble chart visualizes the correlation between life expectancy, population, and GDP per capita for a small set of countries. Each circle's x-axis position encodes life expectancy, its y-axis position encodes population, and its radius and color encode GDP per capita. The visualization uses D3.js (v7) with SVG rendering, and on hover, a tooltip displays the country name. The code applies `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` with an `interpolateTurbo` color scale, and legends for GDP values and country colors. Data comes from the included `bubblechart.csv` file.

Activity 6 task 4

This bubble chart visualizes the relationship between GDP, population, and life expectancy for 14 countries. Each circle’s x-position maps to GDP, y-position to population, and radius to life expectancy, with country labels and hover highlighting. The SVG chart uses D3 v7 with `scaleLinear`, `d3.csv`, and `axisBottom`/`axisLeft`, reading data from an embedded CSV file. The code styles circles with the `.bubble` class and applies opacity changes on mouseover and mouseout events.

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.
