the number of different case status along with time

the number of different case status in different states

This visualization is a heatmap showing the number of immigration case petitions for each case status across different U.S. states, using a red color scale to indicate petition counts. It is built with React and D3 v5, leveraging the vega-lite-api’s `markRect` encoding to map states to the x-axis, case statuses to the y-axis, and petition counts to color intensity. The data comes from the Office of Foreign Labor Certification’s H-1B program records, loaded via `d3.csv`, with tooltips revealing exact counts and statuses.

H1b Data With D3 React

This chart shows the number of H-1B visa petitions filed per year, with bars representing the total count for each year. The visualization uses React components to render SVG elements, with D3 v5 providing the scales and data loading through the `csv` and `scaleBand`/`scaleLinear` APIs. Data comes from the Office of Foreign Labor Certification via a GitHub gist, and the bars are positioned using the x and y scales, with axis labels generated by custom React components.

H1B Petition with Interactive Legend for Case Status

This map visualizes H1B petition case statuses across US locations, with an interactive ordinal color legend that filters and highlights circles by case status on hover. The visualization uses React components, d3.scaleOrdinal for color encoding, and d3.geoPath with geoAlbers projection from the US-Atlas TopoJSON for map rendering. A dropdown allows year selection, while the color legend applies fade opacity to non-selected categories. Data comes from a CSV file loaded via d3.csv, with positions mapped by longitude and latitude coordinates.

H1B Petition with Interactive Legend for Case Status

This example shows H1B petition case statuses as colored circles positioned on a map of the United States. An interactive legend allows hovering over a case status to dim all other statuses and highlight the selected one. The visualization uses React with D3 v5, employing `geoAlbers` and `geoPath` for map projections and `scaleOrdinal` for the color mapping. It renders SVG elements and loads geographic data from the US-Atlas TopoJSON, while petition data comes from a CSV file.

H1b Data with D3 React

This example visualizes the number of H-1B visa petitions across U.S. states, displaying only the top 20 states in descending order as horizontal bars. The chart uses D3 scales (`scaleBand` and `scaleLinear`) within a React component, rendering SVG rectangles via the `Marks` component. Axes are custom-built with `AxisBottom` and `AxisLeft`, and data is loaded asynchronously from a CSV file hosted on GitHub Gist using D3’s `csv` function. The styling applies a Poppins font and teal bar fills.

H1B Petition with Interactive Legend for Case Status

An interactive choropleth map displays the geographic distribution of violent crime rates across US cities. The visualization uses a natural earth projection with graticules and state boundaries rendered via D3's `geoNaturalEarth1`, `geoPath`, and `geoGraticule` APIs. Circle markers sized by the `scaleSqrt` function represent each city's violent crime count, with data loaded from a CSV via D3's `csv` method. The map leverages React hooks for data fetching and renders all SVG elements through a component-based architecture.

This interactive scatterplot displays asylum case wait times (in days) versus entry dates, with a dropdown menu to filter by year. The x-axis dynamically switches between yearly and monthly tick formats based on selection. Using React with D3 v5 scales (scaleTime, scaleLinear), the visualization renders SVG circles with hover tooltips showing exact wait times. Data comes from a CSV of defensive asylum cases, processed with d3.csv and time formatting utilities.

H1b Petition in Different States

This chart displays the number of H-1B petitions filed in each state, with bars segmented by case status (such as certified or denied) using color. The data comes from the Office of Foreign Labor Certification’s immigration program records. Built with D3 and React, the visualization uses the vega-lite-api to define a bar mark with quantitative and nominal encodings, while config.js customizes axis and label styling for improved readability.
