This horizontal bar chart displays the populations of 20 countries in 2010, with each bar labeled by country name and population value, sorted in descending order from China to France. The visualization uses D3.js v7 with an SVG rendering approach, employing `d3.scaleLinear` for the x-axis population scale and `d3.scaleBand` for the categorical y-axis of country names. The code draws axis ticks via `d3.axisLeft` and `d3.axisBottom`, formats population labels with `d3.format('.2s')`, and includes hover effects that change bar colors through CSS.

Question-1.2 Task-1

This horizontal bar chart displays the population of 20 countries in 2010, sorted by country name. The visualization uses React with D3.js scales and axes to render SVG rectangles, with bars sized proportionally to population values. The code imports D3’s `scaleBand`, `scaleLinear`, and `format` APIs, while loading data via `csv` from a GitHub-hosted CSV file. Tooltips show formatted population values using a custom tick format that shortens large numbers to billions.

Question2 task 1

This interactive bar chart displays the populations of 30 countries in 2020, sorted in descending order along a horizontal axis. It uses D3.js to load a CSV from a GitHub repository, process the data, and render an SVG with horizontal bars, a log-scaled x-axis for population values, and a y-axis listing country names. The visualization includes tick marks, axis labels, and hover tooltips for detailed population values.

Activity 6 _Task 1 _ Q.1.2

This horizontal bar chart shows the population of 20 countries in 2010, ordered along a categorical y-axis and scaled linearly on the x-axis. Each light blue bar represents a country’s population, with tick labels formatted in billions (e.g., “1.2B”) using `d3.format`. The visualization uses D3 v7 to create SVG elements, with the `scaleBand` for country categories and `scaleLinear` for population values. Data is loaded asynchronously from a CSV file via `d3.csv`, and axes are rendered using `d3.axisBottom` and `d3.axisLeft`, with custom labels for population and countries.

Task8_Q1)2)

This bar chart displays the population of 20 countries in 2010, ordered along a vertical band scale with horizontal bars extending along a linear population scale. The visualization is rendered as an SVG using React and D3 v5, with data loaded from a CSV file via `d3.csv`. Axes are custom-built using `scaleBand` and `scaleLinear`, while tick labels format population values with the `d3.format` function, converting billions (G) to billions (B). Interactive tooltips appear on each bar via SVG `<title>` elements.

Activity6_task1

This horizontal bar chart displays the 2020 populations of 30 countries, with bars sorted by country name along the y-axis and population values along the x-axis. The visualization uses D3 v7 to load CSV data from a GitHub repository, then renders SVG rectangles with a light green fill. The x-axis uses a linear scale with custom tick formatting to abbreviate large numbers (e.g., 200M, 1.2B), while the y-axis employs a band scale to position the country labels. Axis labels are added via the AxisBottom and AxisLeft components.

Activity6_task1_question2

This horizontal bar chart displays the top 20 countries by population in 2010, sorted in descending order with population values mapped to bar length. The visualization uses D3 v5’s `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis, with `d3.axisLeft` and `d3.axisBottom` rendering the axes. Data is loaded asynchronously via `d3.csv` from a remote gist, and the bars are drawn as SVG `rect` elements. Population values are formatted using `d3.format('.2s')` for compact tick labels.

Activity6_Task1_Q1.2

A horizontal bar chart displays the population of 20 countries in 2010, with country names on the y-axis and population on the x-axis. The data is loaded from a CSV file using d3.csv and rendered as SVG rectangles via d3.select, d3.scaleLinear, and d3.scaleBand. Axis labeling uses d3.axisBottom and d3.axisLeft.

TASK1_2

This horizontal bar chart displays the population figures for 20 countries in 2010, sorted along a categorical y-axis with proportional bar lengths extending along a linear x-axis. The visualization is built with React and D3 v5, using `scaleBand` and `scaleLinear` for positioning, and renders SVG elements through custom `AxisBottom`, `AxisLeft`, and `Marks` components. Data is loaded asynchronously from a CSV file via `d3.csv` and formatted using `d3.format` to abbreviate large numbers as billions, with tooltips showing exact values.
