COVID19 Cases TOP 10 countries-March 19

This visualization displays the total reported COVID-19 cases for the top ten affected countries as of March 19, using a horizontal bar chart. The chart encodes case counts as bar lengths along a linear scale, while country names are arranged on a band scale. Data is loaded from a local CSV file using `d3.csv`. The SVG rendering is built with the D3 v5 API, specifically `select`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom`, with axis tick labels formatted using `format('.2s')`.

Making bar chart

A horizontal bar chart displays COVID-19 case counts per country, with bars ordered by the data’s CSV order. The visualization uses D3 v5’s `scaleBand` for the categorical y-axis, `scaleLinear` for the numeric x-axis, and `axisLeft`/`axisBottom` for gridlines. Data is loaded via `d3.csv` and rendered as SVG rectangles with a steelblue fill, while a clickable “Hello” button triggers a browser alert.

Let's make a face with D3

This example demonstrates how to construct a cartoon face using D3’s SVG manipulation. It renders a static face composed of simple shapes, with styled lines and highlighted paths defined in CSS. The code selects the SVG element via `d3.select` and relies on D3 v5 loaded from a CDN, while the page structure is built with plain HTML. The visualization focuses on basic SVG drawing techniques rather than interactive or data-driven behavior.

Hello VizHub

This example demonstrates a minimal SVG composition: a single thick black line crossing a pink path shape, both rendered against a dark navy background with large, centered text. The page is styled using an external Ubuntu font and a CSS ruleset that sets the color scheme. The static graphic is drawn directly in the index.html markup, while the accompanying JavaScript imports the D3 `select` API to set the text of a message div to "Hello VizHub!", a value defined in a local ES6 module.

report cars

This example displays a static list of car records with attributes such as year, make, model, and price. The code loads data from a local JavaScript module that parses a JSON string into an array of objects. Using D3 v5, it selects an HTML element and sets its text content to display a simple message. The visualization relies on D3’s selection and manipulation methods, along with standard DOM APIs, to render the output within a styled page.
