Forked from task-2

This bubble chart compares GDP per capita with life expectancy for countries worldwide, where each circle’s size reflects population and its color denotes continent. Hovering over a bubble reveals a tooltip with the country name, while focusing on a continent dims all other bubbles to highlight that group. The visualization uses d3.v4 with SVG rendering, d3-scale-chromatic for color schemes, and interactive CSS transitions for hover effects. Data is loaded from a remote CSV file, and scales are defined using d3.scaleLinear and d3.scaleSqrt.

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.

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.

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.

Activity6_task4

This interactive bubble chart visualizes the relationship between happiness scores, GDP per capita, and life expectancy across 30 countries, with bubble size encoding life expectancy and color distinguishing seven global regions. The visualization uses d3.v7 to implement SVG rendering, including scaleOrdinal for regional color mapping, scaleSqrt for bubble sizing, and scaleLinear axes for GDP and happiness dimensions. A tooltip reveals detailed country metrics—including social support, freedom, generosity, and corruption—on hover. The chart reads from a static CSV dataset and employs transition methods to animate tooltip opacity and bubble styling during mouse interactions.

Activity6_Question4

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.

Activity_Task_4

This bubble chart maps GDP against life expectancy for various countries, with bubble size reflecting population and color indicating country. The visualization uses D3 v6 to render an SVG, employing `d3.scaleLinear` for both axes and `d3.scaleSqrt` for bubble radii. Data is loaded from a CSV file via `d3.csv`, which also populates a manual legend. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, and all chart elements—including the title and axis labels—are appended as SVG elements.

Activity6_Task4_Q4

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 all values drawn from the included `bubblechart.csv` file. Hovering highlights a circle with a black stroke. The chart is built using D3 v7, employing `d3.scaleLinear` for axes and radius encoding, rendered as SVG circles, with axis labels generated via `d3.axisBottom` and `d3.axisLeft`.

Activity_6_Task4

A bubble chart maps happiness score against GDP per capita, with circle size encoding life expectancy across 30 countries. Regions are distinguished by color, and hovering reveals detailed country metrics in a tooltip. The visualization is built with D3 v7, using `d3.scaleOrdinal` with `schemeTableau10`, `d3.scaleSqrt` for bubble sizing, and linear scales for both axes. Data comes from a CSV file loaded via `d3.csv`, rendered as SVG elements with animated hover transitions.
