In this article, we are going to create a React app which will show a map without any third-party API. You can edit the map's width and height, add markers to it, and do many more amazing things. We will use the pigeon-maps package to create the map. So, let's get started.ExampleFirst create a React project −npx create-react-app tutorialpurposeNow go to the project directory −cd tutorialpurposeDownload the install the pigeon-maps package −npm install --save pigeon-mapsWe will use this package to add default maps which are downloaded with library inside the React project.Add the following lines of code in App.js −import ...

In this article, we will see how to create a plane in React using React-Three-Fiber. Planes are widely used shapes in 3D rendering. We will create a 2D plane for now, but you can add orbital controls in it to make it 3D. We will also use lighting and different colors. Let's get started.ExampleFirst install the following package −npm i --save @react-three/fiber threethreejs and react-three/fiber will be used to add webGL renderer to the website and three-fiber will be used to connect threejs and React.Add the following lines of code in App.js −import { Canvas } from "@react-three/fiber"; export ...

To compute first of group values, use the groupby.first() method. At first, import the required library with an alias −import pandas as pd;Create a DataFrame with 3 columns −dataFrame = pd.DataFrame( { "Car": ['BMW', 'Lexus', 'BMW', 'Tesla', 'Lexus', 'Tesla'], "Place": ['Delhi', 'Bangalore', 'Pune', 'Punjab', 'Chandigarh', 'Mumbai'], "Units": [100, 150, 50, 80, 110, 90] } )Now, group DataFrame by a column −groupDF = dataFrame.groupby("Car") Compute first of group values and resetting index −res = groupDF.first() res = res.reset_index()ExampleFollowing is the complete code − import pandas as pd; dataFrame = pd.DataFrame( { ...

In this article, we will see how to make a customizable modal in React JS with multiple buttons which can be used in many types of projects like on landing pages or travel websites. A modal is a message box that is displayed on top of the screen. We can use Modals as a subscription box; we can also add animation to a Modal using CSS.ExampleFirst create a React project −npx create-react-app tutorialpurposeGo to the project directory −cd tutorialpurposeDownload and install the react-modal package −npm i --save react-modalWe can use this package to add simple premade modals inside any React ...

"Particle animation" is a technique in game physics, motion graphics, and computer graphics that uses many minute sprites, 3D models, or other graphic objects to simulate certain kinds of "fuzzy" phenomena.In this article, we will see how to make a popular particle animation in React JS. We will do this using a third-party package called "react-tsparticles".First create a React project −npx create-react-app tutorialpurposeGo to the project directory −cd tutorialpurposeExampleDownload and install the "react-tsparticles" package −npm install react-tsparticles reactWe will use this package to add default particle animations with different styling elements. You can also add id and different options for ... Read More
To extract the value names and counts, let us first create a DataFrame with 4 columns −dataFrame = pd.DataFrame({"Car": ['BMW', 'Mustang', 'Tesla', 'Mustang', 'Mercedes', 'Tesla', 'Audi'], "Cubic Capacity": [2000, 1800, 1500, 2500, 2200, 3000, 2000], "Reg Price": [7000, 1500, 5000, 8000, 9000, 6000, 1500], "Units Sold": [ 200, 120, 150, 120, 210, 250, 220] })Fetch the value names and count for a specific column Car −res = dataFrame['Car'].value_counts() Fetch the value names and count for a specific column Units Sold −res = dataFrame['Units Sold'].value_counts()ExampleFollowing is the complete code −import pandas as pd # creating dataframe dataFrame = pd.DataFrame({"Car": ['BMW', ...

To merge Pandas DataFrame, use the merge() function. The one-to-many relation is implemented on both the DataFrames by setting under the “validate” parameter of the merge() function i.e. −validate = “one-to-many” or validate = “1:m”The one-to-many relation checks if merge keys are unique in left dataset.At first, let us create our 1st DataFrame −dataFrame1 = pd.DataFrame( { "Car": ['BMW', 'Lexus', 'Audi', 'Mustang', 'Bentley', 'Jaguar'], "Units": [100, 150, 110, 80, 110, 90] } )Now, let us create our 2nd DataFrame −dataFrame2 = pd.DataFrame( { "Car": ['BMW', 'Lexus', 'Tesla', 'Mustang', 'Mercedes', ...
