What are some popular C++ data visualization tools?

Some popular C++ data visualization tools include Matplotlib, VTK, and Qt Charts. Would you like to know more about any of these?

Can you explain how to use VTK for 3D visualization?

Sure! VTK (Visualization Toolkit) is great for 3D visualization. You can create visualizations by setting up a pipeline of data processing and rendering. Would you like a simple code example?

Yes, please provide a basic example.

Here's a basic example:

#include <vtkSmartPointer.h>
#include <vtkSphereSource.h>
#include <vtkPolyDataMapper.h>
#include <vtkActor.h>
#include <vtkRenderer.h>
#include <vtkRenderWindow.h>
#include <vtkRenderWindowInteractor.h>

int main(int, char *[]) {
    vtkSmartPointer<vtkSphereSource> sphereSource = vtkSmartPointer<vtkSphereSource>::New();
    sphereSource->SetRadius(5.0);
    sphereSource->Update();

    vtkSmartPointer<vtkPolyDataMapper> mapper = vtkSmartPointer<vtkPolyDataMapper>::New();
    mapper->SetInputConnection(sphereSource->GetOutputPort());

    vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New();
    actor->SetMapper(mapper);

    vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New();
    vtkSmartPointer<vtkRenderWindow> renderWindow = vtkSmartPointer<vtkRenderWindow>::New();
    renderWindow->AddRenderer(renderer);
    vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor = vtkSmartPointer<vtkRenderWindowInteractor>::New();
    renderWindowInteractor->SetRenderWindow(renderWindow);

    renderer->AddActor(actor);
    renderer->SetBackground(1, 1, 1); // Background color white
    renderWindow->Render();
    renderWindowInteractor->Start();
    return EXIT_SUCCESS;
}

What other libraries can I use for data visualization in C++?

In addition to VTK, you can use libraries like QCustomPlot, PLplot, and ROOT for data visualization in C++. Each has its own strengths depending on your needs.
