This bubble chart displays the relationship between average PM2.5 levels, average NO2 levels, and population across global cities. The visualization positions each city as a circle along x- and y-axes for the two air quality metrics, while circle size encodes population using d3.scaleSqrt. The chart draws SVG circles with d3.scaleOrdinal color mapping per city, and loads data from a GitHub-hosted CSV via d3.csv. Axes are generated with d3.axisBottom and d3.axisLeft, and the rendering includes labeled axes, stroke outlines, and 0.7 opacity for overlapping bubbles.

Activity6_Question4

This bubble chart shows how average population, area, and temperature correlate across multiple U.S. cities. Each circle’s x-position encodes population, y-position encodes area, radius encodes temperature, and color distinguishes cities. The visualization uses D3 v7 with SVG rendering, linear scales for axes and bubble size, and an ordinal color scale. Interactive tooltips appear on mouseover, while legend circles indicate the temperature-to-radius mapping. Data is loaded from a CSV file.

Activity6_Question4

This bubble chart shows the relationship between GDP and population for 20 global cities, with circle size encoding land area and color distinguishing cities. The visualization uses D3 v6 with SVG rendering, employing `d3.scaleLinear` for the x and y axes, `d3.scaleSqrt` for bubble radius, and `d3.scaleOrdinal` with `schemeCategory10` for color assignment. Interactive hover tooltips display city-specific population and GDP values, while axis labels identify the quantitative variables from the expanded_city_bubble_chart_dataset.csv file.

Activity6_Question4

A bubble chart explores the relationship between population, area, and temperature across Indian cities, with circle size encoding temperature and color distinguishing cities. The visualization uses D3 v7 to load CSV data, render SVG circles, and provide interactive tooltips on hover. It includes linear scales for axes and bubble size, a color scale using interpolateTurbo, and custom legend elements for both temperature values and city names.

Question2_Activity7.1

This is an area chart showing air quality levels over time, displaying two overlapping translucent regions for PM2.5 and PM10 particulate matter concentrations. The visualization uses D3.js v3 with SVG rendering, employing `d3.svg.area()` to construct the filled paths against a time-scaled x-axis via `d3.time.scale()`. Data is loaded from a GitHub-hosted CSV using `d3.csv()`, with dates and times parsed into a unified timestamp. The chart includes a dark blue heading, green axis tick labels, and a blue y-axis label indicating units of µg/m³.

activity6_question9

A bubble chart displays population and GDP for 25 US cities, with bubble size encoding land area. It loads CSV data via `d3.csv` and uses `d3.scaleLinear` for x/y axes and radius, plus `d3.scaleSequential` with `d3.interpolateBlues` for color. Interactive tooltips appear on mouseover, showing city details. SVG rendering includes axes, labels, and a legend for bubble sizes.

Activity6_Question3

This scatter plot visualizes the relationship between pollution levels, life expectancy, and respiratory disease rates across fictional cities. Circles are color-coded by pollution severity (green, orange, red) with radii scaled to respiratory disease prevalence. The visualization uses d3.scaleLinear for x, y, and radius scales, d3.axisBottom and d3.axisLeft for axes, and appends SVG circles via d3.selectAll. Data is hardcoded in the script rather than loaded from the provided CSV file, with axis labels for pollution level.

activity6_question9

A bubble chart compares the population and GDP of 25 major U.S. cities, with bubble size representing city area and color intensity encoding GDP. The visualization uses D3.js v7 to load data from a CSV file and render SVG circles. Interactive tooltips appear on mouseover, showing each city's population and GDP. The chart includes labeled axes, a legend for area, and uses `d3.scaleLinear`, `d3.scaleSequential`, and `d3.interpolateBlues` for encoding.

Activity-6_Question-4

This bubble chart visualizes the environmental impact of urban parks by plotting park area on the x-axis, annual visitors on the y-axis, and tree density as bubble size, with color encoding city. Each circle represents a park from the loaded CSV data, and hovering reveals the park name and air quality index via a tooltip. Built with D3 v7, the visualization uses d3.scaleLinear for axes and bubble radius, d3.scaleOrdinal with d3.interpolateTurbo for city colors, and includes legends for tree density and city categories.
