How to draw horizontal curly braces under a timeline?

Question

I have drawn a timeline using following answer for How draw multiple timelines one after another. Is it possible to add horizontal curly braces under the timeline along with its label?

Desired sketch is as follows:

code for an example timeline:

\documentclass[tikz, margin=3mm]{standalone}
\usepackage{siunitx}
\usetikzlibrary{positioning,calc, arrows.meta}

\begin{document}
\begin{tikzpicture}
  \draw[->, -Latex, line width=1pt] (0,0)node(a){} -- (11,0) node (b) {} ;
  \foreach \x [count=\i] in {0,50,...,500}
  {
    \def \inBetSpace {1}
    \draw[line width=1pt] (\i*\inBetSpace-\inBetSpace,-2mm) node[below](n\i) {\x} -- ++(0,4mm);
  }
\end{tikzpicture}
\end{document}

Answer 1

\documentclass[tikz, margin=3mm]{standalone}
\usepackage{siunitx}
\usetikzlibrary{positioning,calc, arrows.meta}
\usetikzlibrary{decorations.pathreplacing}

\begin{document}
\begin{tikzpicture}
  \draw[->, -Latex, line width=1pt] (0,0)node(a){} -- (11,0) node (b) {} ;
  \foreach \x [count=\i] in {0,50,...,500}
  {
    \def \inBetSpace {1}
    \draw[line width=1pt] (\i*\inBetSpace-\inBetSpace,-2mm) node[below](n\i) {\x} -- ++(0,4mm);
  }
\draw[decorate, decoration={brace, amplitude=6pt},] ([yshift=-1cm]2.95,0)-- node[below=0.25cm]
{Label-1}([yshift=-1cm]a.center);
\draw[decorate, decoration={brace, amplitude=6pt},] ([yshift=-1cm]9,0)-- node[below=0.25cm]
{Label-2}([yshift=-1cm]3.05,0);
\end{tikzpicture}
\end{document}

EDIT using font size \tiny and \scriptsize with font \texttt

\documentclass[tikz, margin=3mm]{standalone}
\usepackage{siunitx}
\usetikzlibrary{positioning,calc, arrows.meta}
\usetikzlibrary{decorations.pathreplacing}

\begin{document}
\begin{tikzpicture}
  \draw[->, -Latex, line width=1pt] (0,0)node(a){} -- (11,0) node (b) {} ;
  \foreach \x [count=\i] in {0,50,...,500}
  {
    \def \inBetSpace {1}
    \draw[line width=1pt] (\i*\inBetSpace-\inBetSpace,-2mm) node[below](n\i) {\x} -- ++(0,4mm);
  }
\draw[decorate, decoration={brace, amplitude=6pt},] ([yshift=-1cm]2.95,0)-- node[below=0.25cm]
{\texttt{\tiny Label-1}}([yshift=-1cm]a.center);
\draw[decorate, decoration={brace, amplitude=6pt},] ([yshift=-1cm]9,0)-- node[below=0.25cm]
{\scriptsize Label-2}([yshift=-1cm]3.05,0);
\end{tikzpicture}
\end{document}
