93f8efc60a Output \n as a string in example code
Current output is:

$ echo "from numpy import random;" \
>      "n = random.randn(10000);"  \
>      "print('\n'.join(str(i) for i in n))"
from numpy import random; n = random.randn(10000); print('
'.join(str(i) for i in n))

After this change, I think it is originally expected string:

$ echo "from numpy import random;" \
>      "n = random.randn(10000);"  \
>      "print('\\\n'.join(str(i) for i in n))"
from numpy import random; n = random.randn(10000); print('\n'.join(str(i) for i in n))

84196c197d Revert "Show message when No input data provided"
Uplot should expect cases where data takes a long time to reach the standard input.
This mechanism is not appropriate.

This reverts commit c40c59a21d.

## Usage
`uplot --help`
```
Program: YouPlot (Tools for plotting on the terminal)
Version: 0.2.7 (using UnicodePlot 0.0.4)
Source: https://github.com/kojix2/youplot
Usage: uplot <command> [options] <in.tsv>
Commands:
barplot bar
histogram hist
lineplot line
lineplots lines
scatter s
density d
boxplot box
colors show the list of available colors
count c baplot based on the number of occurrences
(slower than `sort | uniq -c | sort -n -k1`)
Options:
-O, --pass [VAL] file to output standard input data to [stdout]
for inserting YouPlot in the middle of Unix pipes
-o, --output VAL file to output results to [stderr]
-d, --delimiter VAL use DELIM instead of TAB for field delimiter
-H, --headers specify that the input has header row
-T, --transpose transpose the axes of the input data
-t, --title VAL print string on the top of plot
-x, --xlabel VAL print string on the bottom of the plot
-y, --ylabel VAL print string on the far left of the plot
-w, --width VAL number of characters per row
-h, --height VAL number of rows
-b, --border VAL specify the style of the bounding box
-m, --margin VAL number of spaces to the left of the plot
-p, --padding VAL space of the left and right of the plot
-c, --color VAL color of the drawing
--[no-]labels hide the labels
--fmt VAL xyxy : header is like x1, y1, x2, y2, x3, y3...
xyy : header is like x, y1, y2, y2, y3...
```
Use `--help` to print command-specific options.
`uplot hist --help`
```
Usage: uplot histogram [options] <in.tsv>
Options for histogram:
--symbol VAL character to be used to plot the bars
--closed VAL
-n, --nbins VAL approximate number of bins
Options:
...
```
